Answer:
-1960
Step-by-step explanation:
The expression on the left expands to ...
(4x -7)² = (4x)² +2(4x)(-7) +(-7)² = 16x² -56x +49
Matching coefficients, you have ...
Then the expression c(b+a) evaluates to ...
49(-56+16) = 49(-40) = -1960
The inter-quartile range is the range of the box.
20 - 17

Hope this helps!
Interfere are numbers that can be neagative
Or positive. Rational numbers are numbers that can be put into fractions. Irrational numbers cannot be put into a fraction
First, find the slope of the line contains the points (1,-6) and (-2,6) using slope formula
m =

plug in the numbers
m =

m =

m =

m = -4
Second, determine the slope of perpendicular line
The slope of the perpendicular line is the opposite and reciprocal from the other line. Thus, the slope is
