Answer:

LA = 120 sq cm

SA = 132 sq. cm.

Step-by-step explanation:

LA = ph where p = perimeter of the base and h = the height of prism.

Your base is a triangle. The third side = $\sqrt{5^{2} - 3^{2} }$ = $\sqrt{25 - 9} = \sqrt{16} = 4$

Now, the perimeter of the triangle is 3 + 4 + 5 = 12

So, LA = 12(10) = 120 sq cm

The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6

SA = 2B + LA where B is the area of the base

SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.

Elza [17]

Answer:

3: 2q − 4 = 20

Step-by-step explanation:

Solve for q:

2 q - 4 = 20

Add 4 to both sides:

2 q + (4 - 4) = 4 + 20

4 - 4 = 0:

2 q = 20 + 4

20 + 4 = 24:

2 q = 24

Divide both sides of 2 q = 24 by 2:

(2 q)/2 = 24/2

2/2 = 1:

q = 24/2

The gcd of 24 and 2 is 2, so 24/2 = (2×12)/(2×1) = 2/2×12 = 12:

Answer: q = 12
