HELP PLEASE <br><br> combine like terms to create an equivalent expression

Aneli [31]

The like terms in this expression would be the variables and the numbers without variables. This can be converted into:

$-\frac{6}{5} + \frac{4}{15} - \frac{2}{3}v + \frac{1}{3}v$

And this is $-\frac{14}{15} - \frac{1}{3}v$ .

Answer:

D. 105 ft²

Step-by-step explanation:

The total surface area is the sum of the base area and the triangular face areas.

Area of base:

A = s²

A = (7 ft)² = 49 ft²

Area of 4 triangles:

A = 4(1/2)bh

A = 2(7 ft)(4 ft) = 56 ft²

Total surface area:

base area + triangle area = 49 ft² +56 ft² = 105 ft²
