If you are looking forward to adding them together you will get 145. Just need to know if this questions had options?
Answer:
x=11
Step-by-step explanation:
Using the Exterior Angle Theorem. . .
(3x+8) + (2x+9) = (8x-16)
Solve to get x = 11
27y^3 -343 starts out with 27y^3, and 343 is the cube of 7. Thus, we know immediately that 27y3 -343 is the diffeence of two squares.
The appropriate rule is a^3 - b^3 = (a - b)(a^2 + ab + b^2).
Here, we have 27y3 -343 = (3y - 7)(9y^2 + 12y + 49)
<span>n/100 * 64 = 8 </span><span>n/100 = 8/64<span>
n = 8*100/64 = 25/2 = 12.5</span><span>
8 is 12.5% of 64 hope this helps:)</span></span>
