Step-by-step explanation:
1) Circumference = π*diameter
= 3.14*10 = 31.4 inches
2) 130% of 74 = 1.3 x 74
= 96.2
The volume of the cylinder is <span>552.92</span>
Answer:
x = -23 and -2
Step-by-step explanation:
We can say;
<em>(x + 23) = 0</em>
<em>(2x + 4) = 0</em>
Therefore let's solve the first equation first;
(x + 23) = 0
x + 23 = 0
x = 0 - 23
<u>x = -23</u>
Now let's solve for the second equation;
(2x + 4) = 0
2x + 4 = 0
2x = 0 - 4
2x = -4
x = -4/2
<u>x = -2</u>
Hope this helps!
8y(y - 4) + 3y(y + 2) =
8y^2 - 32y + 3y^2 + 6y =
11y^2 - 26y
