2a² + ab + 2b + 4a² - 3ab + 9
combine like terms:
2a² + 4a² + ab - 3ab + 2b + 9
6a² - 2ab + 2b + 9
Step-by-step explanation:
Given -
Equations
- x + y = 8
- x - y = 3
To Find -
- which pair of coordinates satisfies both equation
Now,
adding both equation, we get -
x + y + x - y = 8 + 3
2x = 11
x = 11/2
<h3>x = 5.5</h3>
Now, substituting the value of x on x + y = 8, we get -
5.5 + y = 8
y = 8 - 5.5
<h3>y = 2.5</h3>
Hence,
(5.5, 2.5) pair of coordinates satisfies both equations.
V=(h)(pi)(r^2)
say pi=3.14
h=15
d/2=r=4/2=2
so
v=(15)(3.14)(2)^2
v=(15)(3.14)(4)
v=(60)(3.14)
v=188.4
so answer is D
