(x-3)(x+5)
Answers
Answer:
x2+5x-3x-15=x2+2x-15
Step-by-step explanation:
(x)(x)=x2,(x)(5)=5x
(-3)(x)=-3x,(-3)(5)=-15
Answer: X^2 + 8x -15
Step-by-step explanation:
Use the foil method.
First, outer, inner, last
Multiply the first numbers inside each parenthesis. X*X = x^2
Next multiply the outer number in each parenthesis. X*5 = 5x
Then multiply the inner numbers of the parenthesis. -3*x= 3x
Finally multiply the last numbers in the parenthesis. -3*5 = -15
Now add all of these together
X^2 + 5x + 3x + -15
Combine like terms
X^2 + 8x -15
X can be solved from here, however it does not seem that you are asked to solve for x

How does x = 0.7x + 24 equal 80?
Answers
Answer:
x=0.7x+24
We move all terms to the left:
x-(0.7x+24)=0
We get rid of parentheses
x-0.7x-24=0
We add all the numbers together, and all the variables
0.3x-24=0
We move all terms containing x to the left, all other terms to the right
0.3x=24
x=24/0.3
x=80
And that's how you get 80
Step-by-step explanation:
i hope this helps. :)
Answer: x = 80
Step-by-step explanation:
80 - 24 = 56
56 divided by 0.7 = 80
If n + 7 = 10, evaluate 2n - 2
O 3
0 17

6
Answers
Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
[tex]n + 7 = 10[/tex]
Subtract 7 from both sides of the equation
[tex]n+7-7=10-7[/tex]
Simplify
[tex]n=3[/tex]
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.

supppose v varies direcly as g, and v= 36 when g=4. Find v when g =11
Answers
Answer:
v = 99
Step-by-step explanation:
Given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
To find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
When g = 11 , then
v = 9 × 11 = 99
