Answer:
Area of the 2 circles
= 2 pi r square root
= 2 x 3,14 x 21 x 21
=6,28 x 441
=2769.48inches square
Area of the rectangle
= L x h
= where is the other number bc then u cant solve it
Step-by-step explanation:
Answer:
The y intercept to this problem is;
(0,7)
Explanation:
To find the x-intercept, substitute in 0 for y and solve for x . To find the y-intercept, substitute in 0 for x and solve for y .
Subtract 2x from both side
X = 5
The solution is 5
You need to round the number to the nearest whole number
Answer:
b=-19
Step-by-step explanation:
We know that one of the solutions is x=-4/5
That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.
5(-4/5)^2+b(4/5)+12=0
Now, just solve for b.
5(16/25)+b(4/5)+12=0
(16/5)+(4/5)b+12=0
(76/5)+(4/5)b=0
(4/5)b=-(76/5)
b=-19
