Answer:
[tex]4x^2-x+8[/tex]
Step-by-step explanation:
First expand [tex](x-8)^2[/tex].
[tex](x-8)(x-8)=x^2-16x+64[/tex]
Now Add:
[tex](x^2-16x+64)+(3x^2+15x-56)\\(x^2+3x^2)+(-16x+15x)+(64-56)=\\4x^2-x+8[/tex]
We want this:
3x^2 + 15x - 56 + (x - 8)^2
First, expand (x - 8)^2 using FOIL.
So, (x - 8)^2 = (x - 8)(x - 8).
(x - 8)(x - 8) = x^2 - 16x + 64.
We now add like terms.
3x^2 + 15x - 56 + x^2 - 16x + 64
4x^2 - x + 8
Done.

Renee’s workout consists of biking and running. While biking she burns 10 calories per minute, and while running she burns 15 calories per minute. Renee wants to burn at least 900 calories each day.
Let x be the number of minutes she spends biking and let y be the number of minutes she spends running. Write an inequality that models this situation.
Answers
Answer:
10x + 15y ≥ 900
Step-by-step explanation:
She burns 10 calories per minute while biking and 15 calories per minute while running. For each exercise, the number of minutes multiplied by the number of calories burned per minute will give the total number of calories burned.
Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).
The inequality that models this situation is therefore
10x+15y≥900
The required inequality that models the given situation is 10x + 15y ≥ 900.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
While biking, she burns 10 calories per minute, and 15 calories per minute while running. The total number of calories burned for each exercise is the number of minutes multiplied by the number of calories burned per minute.
Let x be the number of minutes she spends biking and let y be the number of minutes she spends running.
Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).
As per the given situation, the required inequality would be as:
⇒ 10x + 15y ≥ 900
Thus, the required inequality that models the given situation is 10x + 15y ≥ 900.

Step-by-step explanation:
Gonna solve it but you need to do the rest, the answers are all in the solution.
Expand the following:
(3 (x + 2) = 18, 3 x + 6 = 18)
3 (x + 2) = 3 x + 3 2:
((3 x + 3 2) = 18, 3 x + 6 = 18)
3×2 = 6:
(3 x + 6 = 18, 3 x + 6 = 18)
Subtract 6 from both sides:
(3 x + (6 - 6) = 18 - 6, 3 x + 6 = 18)
6 - 6 = 0:
(3 x = 18 - 6, 3 x + 6 = 18)
18 - 6 = 12:
(3 x = 12, 3 x + 6 = 18)
Divide both sides of 3 x = 12 by 3:
((3 x)/3 = 12/3, 3 x + 6 = 18)
3/3 = 1:
(x = 12/3, 3 x + 6 = 18)
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:
(x = 4, 3 x + 6 = 18)
Subtract 6 from both sides:
(x = 4, 3 x + (6 - 6) = 18 - 6)
6 - 6 = 0:
(x = 4, 3 x = 18 - 6)
18 - 6 = 12:
(x = 4, 3 x = 12)
Divide both sides of 3 x = 12 by 3:
(x = 4, (3 x)/3 = 12/3)
3/3 = 1:
(x = 4, x = 12/3)
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:
Answer: (x = 4, x = 4)
Find all possible values of each expression. Suppose 3
Answers
The inequality that describes the possible values of the expression is:
[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]
What is the lower bound of values of the expression?The expression is given by:
[tex]\frac{b}{3a} - \frac{a}{3b}[/tex]
To find the lower bound, we try to see when the expression is negative, hence:
[tex]\frac{b}{3a} - \frac{a}{3b} < 0[/tex]
[tex]\frac{b}{3a} < \frac{a}{3b}[/tex]
Applying cross multiplication and simplifying the 3's, we have that:
[tex]b^2 < a^2[/tex]
From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
What is the upper bound of values of the expression?The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Maximize b, hence b = 5.Minimize a, hence a = 4.Then:
[tex]\frac{b}{3a} - \frac{a}{3b} = \frac{5}{12} - \frac{4}{15} = \frac{25 - 16}{60} = \frac{9}{60}[/tex]
Hence the bounds are:
[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]

How far of a walk does she have to get to Trout Street?
Diagram shows triangle with base side labeled boardwalk and 2 legs labeled Trout Street and Salman Street. Segment labeled 1st street drawn from top vertex to base side is at right angle. Distance between segment and bottom right vertex is 800 yards.
Abby's walk to Trout Street is
yards.
Answers
When Abby's walk to Trout Street is 800 yards.
Distance is referred to as the length of a moving particle's real path. The shortest distance between a body's initial and final positions is referred to as displacement.
The distance between the segment and bottom right vertex is 800 yards.
The 1st street, Trout Street, and Salmon Street intersect at a point G.
Now, Trout street and Salmon street are at the same distance from the boardwalk.
From the figure, the distance between the boardwalk and salmon street is 800 yards.
Now the 1st street is perpendicular to line AE which is the distance between Trout street and Salmon street and hence AC = CE.
Therefore, When Abby's walk to Trout Street from the boardwalk is 800 yards.

A student put $1,200 in a savings account paying simple interest of 4.5% per year. Find the total amount of the student's savings after 5 years. A: $700. B: $1470. C: $1000. D: $400
Answers
Answer:
(B) $1470
Step-by-step explanation:
Given that the principal initial amount, p=$1200
Rate of simple interest per year, r=4.5% = 0.045
Time, t=5 years
Interest after 5 years,
I=prt= 1200 x 0.045 x 5 = 270
Total amount = Principal initial amount + Interest
=1200+270=1470
So, the total amount of the student's savings after 5 years is $1470.
Hence, option (B) is correct.
