a square was altered so that one side is increased by 9 inches and the other side is decreased by 2 inches. the area of the resulting rectangle is 60 square inches. What was the are f the original square.
Answer:
36 square inches.
Step-by-step explanation:
Since the original figure was a square, all four side lengths are equivalent. The area for the square will be:
[tex]A=s^2[/tex]
Where s is the length of one side.
One side is increased by nine inches and the other side was decreased by two inches. The area of the resulting rectangle is 60 square inches.
So, one of the new sides is (s + 9).
And the other is (s - 2).
The area with these dimensions is 60. Thus:
[tex]60=(s-2)(s+9)[/tex]
Solve for s. Distribute:
[tex]60=s^2+7s-18[/tex]
Isolate the variables:
[tex]s^2+7s-78=0[/tex]
Factor:
[tex](s+13)(s-6)=0[/tex]
Zero Product Property:
[tex]s+13=0\text{ or } s-6=0[/tex]
Solve for each case:
[tex]s=-13\text{ or } s=6[/tex]
A side length cannot be negative. So, our only solution is:
[tex]s=6\text{ inches}[/tex]
Since each side of the square measures six inches, the area of the original square will be 36 square inches.
E is route 30
Please help mee
Answer:
Options A, D and E
Step-by-step explanation:
If a number in square root can't be solved Or square root of the number can't be removed then it is a surd.
Option A
√17 = Surd [Can't be simplified further]
Option B
√36 = 6
Not a surd
Option C
√100 = 10
Not a surd
Option D
√15 = Surd
Option E
√30 = Surd
Therefore, Options A, D and E are the surd.

Quadrilateral ABCD is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?
Answer:
BE=15
Step-by-step explanation:
Since E is the center, BE=2x+1
And AC is 6x-12 with E being a midpoint.
Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that
you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE
6x-12=4x+2
BD=AC
6x-4x-12=2
2x=2+12
2x=14
x=7
BE= 2x+1
2(7)=14+1=15

if 6x+4=20-2x, then 8x=?
Answer:
8x = 16 x=2
Step-by-step explanation:
Answer: Simplifying
8x = 0
Solving
8x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 0
Simplifying
x = 0

PLEASE HELP WILL GIVE BRAIN Which could be the function of the following graph?
f(x) = (x + 5)^3(x + 1)^2(x - 2)^2 f(x)=(x+5)3(x+1)2(x−2)2
f(x) = (x + 5)^2(x + 1)(x - 2)^3 f(x)=(x+5)2(x+1)(x−2)3
f(x) = (x + 5)^3(x + 1)^2(x - 2)^2(x - 5) f(x)=(x+5)3(x+1)2(x−2)2(x−5)

WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)

Answer:
([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)
Step-by-step explanation:
Using the factorising method, difference of 2 squares
a² - b² = (a - b)(a + b) , then
5n² - 16
= ([tex]\sqrt{5}[/tex] n )² - 4²
= ([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

I need help finding the rate of change can someone help me
Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.
