Answer:
95 square units
Step-by-step explanation:
Surface area of pyramid = 4(side area) + base
Solve for the base first.
Area of base = s*s = 5*5 = 25
Next solve for one of the sides.
Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5
Plug these back into our original equation.
Surface area of pyramid = 4(side area) + base
Surface area of pyramid = 4(17.5) + 25
Surface area of pyramid = 70 + 25 = 95 square units
37 to the nearest tenth is 40.
Answer:
<h3>16a + 20</h3>
Step-by-step explanation:
4(4a + 5) <em>use distributive property</em>
= (4)(4a) + (4)(5) = 16a + 20
11+5=16 3x2= 6 8x1= 8 so add it together, 16 + 6 + 8 = 30.
