<u>Answer:</u>

The correct answer option is B. 1/5.

<u>Step-by-step explanation:</u>

We are given four fractions in the answer options and we are to determine whether which one of them has terminating decimal as its decimal expansion.

Terminating decimal means a decimal value which has a finite amount of numbers and has an end to it.

\frac{1}{3} = 0.333333333

\frac{1}{5} = 0.2

\frac{1}{7} = 0.142357142

\frac{1}{9} = 0.111111111

Therefore, the correct answer is 1/5.

EF= 2x-6 and FG= 4x+7. when you plug that in it should look like this 25=2x-6+4x+7 then solve.

A triangle has an area of 36 square feet. If the height of the triangle is 6 more feet than its base, what is its height and bas
andriy [413]
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.

Eva8 [605]

Given:

The given expression is:

(-4x+9)^2

According to Kylie,

(-4x+9)^2=(-4x)^2+(9)^2

(-4x+9)^2=16x^2+81

To find:

The correct statement for Kylie's explanation.

Solution:

We have,

(-4x+9)^2

According to the perfect square trinomial (a+b)^2=a^2+2ab+b^2.

(-4x+9)^2=(-4x)^2+2(-4x)(9)+(9)^2

(-4x+9)^2=16x^2-72x+81

Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.

Therefore, the correct option is C.
