What is the surface area of the prism in square feet?

frutty [35]

The surface area of the rectangular prism is 52 square feet ( $ft^{2}$ ), if the height is 4 feet, width is 3 feet and depth is 2 feet.

Step-by-step explanation:

The given is,

A rectangular prism of

Let, h - height of the rectangular prism

w - Width of the rectangular prism

d - Depth of the rectangular prism

Step:1

From given,

h = 4 feet

w = 3 feet

d = 2 feet

Step:2

Formula to calculate the surface area of the rectangular prism is,

$A = 2 (wd+hd+hw)$

Substitute the values of w,d and h

= 2 [(3×2) + (4×2) + (4×3)]

= 2 (6+8+12)

= 2 × 26

= 52

A = 52 Square feet

Result:

Thus the surface area of the rectangular prism is 52 square feet ( $ft^{2}$ ), if the height is 4 feet, width is 3 feet and depth is 2 feet.

F(x)= 3x - 4x2 +6x and g(x)= 5x +2x2 – 3x. What is f(x) g(x)?

goldenfox [79]

f(x)g(x) = 9x² + 10x - 16

Step-by-step explanation:

Step 1:

Given f(x) = 3x - 4 × 2 + 6x and g(x) = 5x + 2 × 2 - 3x

f(x) = 9x - 8

g(x) = 2x + 4

f(x)g(x) = (9x - 8)(2x + 4)

= 18x² + 36x - 16x -32

= 18x² + 20x - 32

= 9x² + 10x - 16

Tony bowled 135 and 145 in his first two games. write and solve a compound inequality to find the possible values for a third ga

stira [4]

The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130

In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
