Answer:
idk dont ask me
Step-byi-step explanation:
The height of the rectangular prism. given its volume and base area is (3x³ + 16x² + 5x) / (x² + 5x) units.
<h3>Volume of rectangular prism</h3>
- Volume of the prism = 3x³ + 16x² + 5x cubic units
- Base area = x² + 5x square units
Volume of a rectangular prism = Base area × height
Height = Volume of a rectangular prism ÷ Base area
3x³ + 16x² + 5x cubic units = (x² + 5x) square units × h
h = (3x³ + 16x² + 5x) cubic units ÷ (x² + 5x) square units
h = (3x³ + 16x² + 5x) / (x² + 5x) units

Answer:
(x, y) = (3.5, -4)
Step-by-step explanation:
Elimination is easiest if one of the coefficients of a variable is a multiple of the other coefficient of the variable. Here, we have x-coefficients of 4 and 8, so it will be easiest to eliminate x.
Subtract the second equation from 2 times the first.
2(4x +7y) -(8x +5y) = 2(-14) -(8)
9y = -36 . . . . . simplify
y = -4 . . . . . . . divide by 9
4x +7(-4) = -14 . . . . substitute for y in the first equation
4x = 14 . . . . . . . add 28
x = 3.5 . . . . divide by 4
The solution is (x, y) = (3.5, -4).
Answer:
304 IN
Step-by-step explanation:
total inches needed for necklace : 38 x 5 = 190
total inches needed for necklace : 38 x 3 = 114
190 + 114 = 304 inches
Answer:
n=-15
Step-by-step explanation:
5=n/5+8
subtract 8 on both sides
-3=n/5
multiply 5 on both sides
-15=n
