10.) DC
community property
11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)
The surface area of the triangular prism is 93 squared feet.
<h3>What is the
surface area of the
triangular prism?</h3>
The surface area of triangular prism is expressed as;
S.A = bh + ( s₁ + s₂ + s₃ )H
From the diagram;
- h = 2ft
- b or s₁ = 3ft
- s₂ = 3ft
- s₃ = 3ft
- H = 10ft
We substitute our given values into the equation above.
S.A = bh + ( s₁ + s₂ + s₃ )H
S.A = (3ft × 2ft) + ( 3ft + 3ft + 3ft )10ft
S.A = 3ft² + ( 9ft )10ft
S.A = 3ft² + 90ft²
S.A = 93ft²
The surface area of the triangular prism is 93 squared feet.
