Simplify the expression: 5x + 8 – 13y – 4x – 18 + 16y

aleksandrvk [35]

$\text{Hey there!}$

$\text{Simply the equation: 5x + 8 - 13y - 4x - 18 + 16y}$

$\text{First you have to combine the \bf{like-terms}}$

$\text{5x-4x = 1x}$

$\text{-13y + 16y = 3y}$

$\text{8 + (-18) = -10}$

aleksklad [387]

Answer:

268+v2)3+p=8 =p=−3v2−796

Step-by-step explanation:

Let's solve for p.

(268+v2)(3)+p=8

Step 1: Add -804 to both sides.

3v2+p+804+−804=8+−804

3v2+p=−796

Step 2: Add -3v^2 to both sides.

3v2+p+−3v2=−796+−3v2

p=−3v2−796

Hope this helps.

Step-by-step explanation:

A cube has 6 congruent square faces

The area of 1 face = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$

Multiply by 6 to obtain surface area of cube

surface area = 6 × $\frac{4}{9}$ = $\frac{24}{9}$ = $\frac{8}{3}$ units²
