Answer:
AB = 60
Step-by-step explanation:
Given AC = 75 and AB = 4BC, then
AB + BC = AC, that is
4BC + BC = 75
5BC = 75 ( divide both sides by 5 )
BC = 15
Thus
AB = 4BC = 4 × 15 = 60

Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m =
=
= - 
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
Answer:
A = 84 
Step-by-step explanation:
To find the area of a trapezoid, use this equation:

a = top base
b = bottom base
h = height
Let's classify all the sides:
a = 4 ft
b = 10 ft
h = 12 ft
Now, let's plug all these into the equation:

Add what's in the numerator
Divide 14 by 2
A = 84
Multiply 7 by 12
So, the area of the trapezoid is 84
.
Hope this helps!!
