Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
Answer:
so b=-9 while c=12.
Step-by-step explanation:
If you have x-intercepts 1 and -4, then that means f(1)=0 and f(-4)=0.
You are given
So you have the system of equations to solve:
Evaluating the exponents:
Doing a little bit of multiplying:
Let's add 3 on both sides of equation 1 and 48 on both sides of equation 2:
Subtracting the equations will eliminate c.
Let's do that:
Divide both sides by 5:
Simplify:
If b=-9 and b+c=3 then -9+c=3 implies c=9+3=12.
so b=-9 while c=12.
For x=1
h(2)=h(1)+h(0)
h(2)=12+3
h(2)=15
for x=2
h(3)=h(2)+h(1)
h(3)=15+12
h(3)=27
for x=0
h(1)=h(0)+h(-1)
12=3+h(-1)
h(-1)=12-3
h(-1)=9
