Answer:
6 inches by 6 inches
Step-by-step explanation:
Area of the square = 256 inches ²
Given equation:
(x + 10)² = 256
Where,
x = side measure of the original square
(x + 10)² = 256
(x + 10)(x + 10) = 256
x² + 10x + 10x + 100 = 256
x² + 20x + 100 = 256
x² + 20x + 100 - 256 = 0
x² + 20x - 156 = 0
Solve the quadratic equation by factorization
Find two numbers whose product is -156 and sum is 20
The numbers are -26 and 6
x² + 26x - 6x - 156 = 0
x(x + 26) - 6(x + 26) = 0
(x + 26) (x - 6) = 0
x + 26 = 0 or x - 6 = 0
x = -26 or x = 6
Side length of a square can not be negative
Therefore,
x = 6 inches
6 inches by 6 inches

Step-by-step explanation:
Answer:
110,618,000A
Step-by-step explanation:
we don't know the area or side A, so it's the other sides multiplied and then the unknown variable multiplied by it as well.
The answer would be c because I know
First we need to find the slope of the line.
slope = y1-y2/x1-x2 = 4-1/3-(-3) = 3/6 = 1/2
So, the slope is 1/2
Now, we need to find the y-intercept by using the equation y=mx+b
y=mx+b
4=1/2(3)+b
4=3/2+b
-3/2 -3/2
5/2=b
So, the equation is y=1x/2+5/2 which is also C. y-3=1/2(x+1)
