Answer:

G. $\frac{3.2}{2} = \frac{a}{8}$

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

$\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}$

Therefore, the proportion that must be true is:

✔️ $\frac{3.2}{2} = \frac{a}{8}$

Find (w² + 1)(w³ - w + 1).

Citrus2011 [14]

Answer:

Product is $w^5+w^2-w+1$

Step-by-step explanation:

Given: $(w^2+1)(w^3-w+1)$

Simplify the product of polynomial.

It is product of binomial with trinomial.

$\Rightarrow (w^2+1)(w^3-w+1)$

$\Rightarrow w^2(w^3-w+1)+1(w^3-w+1)$ (Distributive property)

$\Rightarrow w^2\cdot w^3-w^2\cdot w+w^2\cdot 1+w^3-w+1$ (Distributive property)

$\Rightarrow w^5-w^3+w^2+w^3-w+1$ (combine like term)

$\Rightarrow w^5+w^2-w+1$

Product is $w^5+w^2-w+1$

What is the surface area of a rectangular prism that has dimensions of: Length is 6.5, width is 8, and the height is 3.8

stich3 [128]

Answer:

214.2 units²

Step-by-step explanation:

To find the surface area, we add the area of all the 6 sides.

2(Length x Width) + 2(Length + Width) x height

Surface area

= 2(6.5 x 8) + 2(6.5 + 8) (3.8)

= 104 + 110.2

= 214.2 units²
