If the perimeter is 284, what is the value of a? <br> Please show work xx
devlian [24]

Answer:

8

Step-by-step explanation:

Perimeter is 284 means the sum of the side measurements is 284.

That is, we have to solve:

(6a+8)+(12a)+(10a-4)+(6a+8)=284

Combine like terms:

(6a+12a+10a+6a)+(8+0+-4+8)=284

Simplify:

34a+12=284

Subtract 12 on both sides:

34a=284-12

Simplify:

34a=272

Divide both sides by 34:

a=\frac{272}{34}

Simplify:

a=8

10. The volume of the triangular prism is V=A_{base}\cdot H=\dfrac{1}{2} height \cdot base\cdot H, then

V=\dfrac{1}{2} \cdot 4\cdot 3.5\cdot 3.3=23.1.

11. The volume of the triangular pyramid is V=\dfrac{1}{3}A_{base}\cdot H=\dfrac{1}{3}\cdot \dfrac{1}{2} height \cdot base\cdot H, then

V=\dfrac{1}{3}\cdot \dfrac{1}{2} \cdot 4\cdot 3.5\cdot 3.3=7.7.

12. They have common base (common triangle). y=7.7, r=23.1, then r:y=23.1:7.7=3.

13. See 10 and 11 for notations in symbols.
