The answer is SR=3
2x+23+x+21=14
Solve for x you get
x=-10
Substitute x
2(-10)+23=3
The answer would be the square root of 25 times 9 im pretty sure its been while and it would be 25*9=225 square root of 225 is 15
Answer:
26; the cheetah's rate in miles per hour
Step-by-step explanation:
Using the quadratic equation we get:
Factoring out 2 we get
Factoring out the imaginary number:
So b.
Let s represent the length of any one side of the original square. The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.
The area of this rectangle is (s+9)(s-2) = 60 in^2.
This is a quadratic equation and can be solved using various methods. Let's rewrite this equation in standard form: s^2 + 7s - 18 = 60, or:
s^2 + 7s - 78 = 0. This factors as follows: (s+13)(s-6)=0, so that s = -13 and s= 6. Discard s = -13, since the side length cannot be negative. Then s = 6, and the area of the original square was 36 in^2.
