Step-by-step explanation:
8x2 + 16x + 3 = 0
a is 8 b is 16 c is 3
multiply 8 and 3 = 24
what 2 numbers when multiplied make 24 and when added make 16?
use quadratic formula
a is 8 b is 16 c is 3
x= (-b +- (√b^2-4ac))/2a
x= (-16 +- (√b^2-4(8)(3)))/2(8)
x= (-16 +- (√16^2-96))/16
x= (-16 +- (√256-96))/16
x= (-16 +- (√160))/16
x= (-16 +- (4√10))/16
x= -1 +- (√10/4)
split up the + and -
x= -1 - √10/4 = -0.209431
x= -1 + √10/4 = -1.79057
Answer:
The average selling price of each trailer was nearly $922
Step-by-step explanation:
University trailer sales company sold 356 utility trailers during a recent year.
If the gross annual sales for the company was $328,132.
For the average selling price of each trailer, we will divide <em>the gross annual sales </em>by <em>utility </em><em>trailers.</em>
= 328132 ÷ 356
= 921.7 ≈ 922
Thus, The average selling price of each trailer was nearly $922

Answer:see the picture to better understand the problem
we know that
scale factor=12/8----> 1.5
volume larger pyramid=scale factor³*volume smaller pyramid
scale factor=1.5
volume smaller pyramid=52 in³
so
volume larger pyramid=1.5³*52-----> 175.5 in³
the answer is
175.5 in³
