Answer:
(5x-2)(5x+2)
Step-by-step explanation:
Differences of squares is basically (a2-b2) = (a-b) (a+b)
a = 5x and b = 2 in this case
Brainliest is appreciated :)
Answer:
y = x - 3
Step-by-step explanation:
From the table attached,
Scatter plot given in the graph is correct.
Let the equation of the line passing from a point (x', y') is,
y - y' = m(x - x')
m = slope
Slope of the line passing through two points
and
is given by,
m = 
Therefore, slope of the line passing through the points (11, 8) and (12, 9) will be,
m = 
Therefore, equation of the line passing through (11, 8) will be,
y - 8 = 1(x - 11)
y = x - 11 + 8
y = x - 3
Answer:
The length of side is 42.4 inches.
Step-by-step explanation:
Given that:
Diagonal of square = 60 inches
As all sides of a square are equal, thus
Side of square = x
The diagonal will be the hypotenuse of a right angled triangle.
Using Pythagorean theorem;

Taking square root on both sides

Hence,
The length of side is 42.4 inches.
Answer:
210 miles
Step-by-step explanation:
30x7=210
<u>Answer</u>
y = (1/2)x - 1
<u>Explanation</u>
The first step is to get the gradient of the line.
The two points in the line are; (2,0) and (-2, -2).
Gradient = (-2 - 0)/(-2, - 2)
= -2/-4
= 1/2
To get the function we use one of the point (2,0) and a general point (x,y).
1/2 = (y - 0)/(x - 2)
1/2 = y/(x - 2)
(x - 2) = 2y
2y = x - 2
y = (1/2)x - 1
