What is 5% of $37.95

Answer:

x+9

Step-by-step explanation:

4x³+12x²-72x

=4x(x²+3x-18)

=4x[x²+6x-3x-18]

=4x[x(x+6)-3(x+6)]

=4x(x+6)(x-3)

Answer:

Yes it is

Step-by-step explanation:

4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).

The answers are A, E and F because the amount Darren's friend adds to his savings each week is a faster rate or higher amount than $40 dollars:

y = 75x(higher than 40) + 120

y = 120 + 50x(higher than 40)

y = 87x(higher than 40) + 120

Answer:

We conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]

Step-by-step explanation:

Given the radical expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

simplifying the expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

Remove parentheses:  (-a) = -a

[tex]\sqrt{\left(-81\right)x^2}=\sqrt{-81x^2}[/tex]

Apply radical rule:   [tex]\sqrt{-a}=\sqrt{-1}\sqrt{a},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                 [tex]=\sqrt{-1}\sqrt{81x^2}[/tex]

Apply imaginary number rule:  [tex]\sqrt{-1}=i[/tex]

                 [tex]=i\sqrt{81x^2}[/tex]

Apply radical rule:   [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]

                  [tex]=\sqrt{81}i\sqrt{x^2}[/tex]

                  [tex]=9i\sqrt{x^2}[/tex]

Apply radical rule:  [tex]\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                  [tex]=9ix[/tex]

Therefore, we conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]

Step-by-step explanation:

The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.

Given that, we are asked to find the expanded form of 8.478,

The expanded form is :-

8 =  1 place = 8×1

0.4 = 1/10 place = 4×1/10

0.07 = 1/100 place = 7×1/100

0.008 = 1/1000 place = 8×1/1000

Therefore,

8.478 = 8×1+4×1/10×7×1/100+8×1/1000

Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

Answer:

the answer is (x,y) (1/4 -13/4)

Answer:

1 5/32

Step-by-step explanation:

First, find common denominators. What you do to the denominator, you must do to the numerator.

First, multiply 4 to both the numerator and denominator of the second fraction:

(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32

Next, add across:

9/32 + 28/32 = 37/32

Simplify. Turn the improper fraction into a mixed fraction:

37/32 = (32 + 5)/32 = 1 5/32

1 5/32 is your answer.

~

Answer:

37 /32

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 8 and 32 is 32

For the 1st fraction, since 8 × 4 = 32,

7 /8  =  7 × 4

       8 × 4 =  28 /32

Likewise, for the 2nd fraction, since 32 × 1 = 32,

9 /32  =  9 × 1

          32 × 1 =  9 /32

Add the two fractions:

28 /32 +  9/32 =  28 + 9 /32  =  37 /32

So, 7/8 + 9/32 = 37/32

In mixed form: 1 5 /32

Answer:

Step-by-step explanation:

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

h is height

b is base

Put in the values you know

Multiply

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Answer:

30

Step-by-step explanation:

Add all the measures 50+35+85+65+60= 210

subtract 180 from 210 and you get

210-180 = 30

we use 180 because  Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.
