Step-by-step explanation:
It will be 18
Answer:
area of the original square = 36 in²
Step-by-step explanation:
given data
one side is increased = 9 inches
other side is decreased = 2 inches
area of the resulting rectangle = 60 in²
solution
we consider here x as the length of any one side
and
longer side of the resulting rectangle = x + 9
and
the shorter side x - 2
so that area of this rectangle is (s+9) × (s-2) = 60 in²
standard form of equation is x² + 7x - 18 = 60 .....................1
it will be
x² + 7x - 78 = 0
(s+13) (s-6) = 0
so that here x = -13
and x = 6
here we Discard x = -13 because the side length cannot be negative.
so x = 6
and area of the original square = 36 in²
Answer:
A; y- 4 = -2(x + 1)
Step-by-step explanation:
Here, we want to find the equation of the given line
The general form
is ;
y = mx + c
c is the y-intercept which is 2
So we have
y = mx + 2
The x-intercept where y = 0 is 1
Thus;
0 = m(1) + 2
0 = m + 2
m = -2
So the equation of the line is
y = -2x + 2
We can rewrite this in the point-slope form as:
y - 4 = -2(x + 1)
Answer: It would be the number 1 since they all cancel each other out
