The width of a rectangle is 1units less than the length. The area of the rectangle is 42 units

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

no not all of them.

step-by-step explanation:

some of them have a square base.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
