8x - 9x²y + 7y² - 2x⁴
-2x⁴ - 9x²y + 8x + 7y²
Answer:
Step-by-step explanation:
Givens
pi = 3.14
d = 3.8
r = d/2
r = 3.8/2 = 1.9
Formula
V = (4/3) * pi * r^3
Solution
V = (4/3) * 3.14 * 1.9^3
V = 4/3 * 3.14 * 6.859
V = 28.7163
It represents that because multiplication is like adding continually so it represent 8+8+8+8 which is 8 x 4

7x - 3 = 60
7x = 63
x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5
Answer: I’m pretty sure the answer is 1 1/9
Step-by-step explanation:
The exact form is 10/9
x=1.1
X=1 1/9
