The answer is a. -7

1. Find g(2).

2. Find f(g(2)).

g(x) = x² - 6x - 7

x = 2 ⇒ g(2) = ?

g(2) = 2² - 6·2 - 7 = 4 - 12 - 7 = -15

2. f(x) = x + 8

g(2) = -15

f(g(2)) = f(-15) = -15 + 8 = -7

A rectangular prism has a base length of 6 units, base

Maurinko [17]

Answer:

The lateral area rectangular prism is $88 unit^2$ .

The area of the two bases of rectangular prism together is $60 unit^2$ .

The total surface area rectangular prism is $148 unit^2$ .

Step-by-step explanation:

Height of the rectangular prism = h = 4 units

Length of the base of the rectangular prism = l = 6 units

Width of the base of rectangular prism = b = 5 units

Rectangular prism = Cuboid

Lateral surface area of cuboid = L.S.A = 2 × h × (l+b)

Lateral surface area of rectangular prism :

$L.S.A=2\times 4 units(6 units+5units)=88 units^2$

Area of the base = l × b

Area of the base of the rectangular prism = $6 unit\times 5 unit=30 unit^2$

Area of the two bases = $2\times 30 unit^2=60 unit^2$

Total surface area of cuboid = T.S.A = 2 ×(lb+bh+hl)

Lateral surface area of rectangular prism :

$T.S.A=2\times (6unit\times 5unit+5 unit\times 4unit+4 unit\times 6 unit)$

$=148 unit^2$
