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

I need help finding the rate of change can someone help me
Answers
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.

Quadrilateral ABCD is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?
Answers
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

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.
Answers
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.

Answer:
Step-by-step explanation:
The sum of the three interior angles of a triangle is always 180.
Knowing this, we can set up an equation for the given angles:
[tex]8x + 10x + 12x = 180[/tex]
[tex]30x = 180[/tex]
[tex]x = 6[/tex]
Knowing this, we can now plug it into the angles:
