You'll want to first simplify the expression

.
To do that, first distribute the

:


From there, you may just combine like terms:




Answer:
D. 4t - 10
Answer:
1:3
Step-by-step explanation:
Please study the diagram briefly to understand the concept.
First, we determine the height of the isosceles trapezoid using Pythagoras theorem.

The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.
Area of a trapezoid 
Area of the trapezoid

For an equilateral triangle of side length s.
Area 
Side Length of the smaller triangle, s= 4 Units
Therefore:
Area of the smaller triangle

Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid

Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.

Answer:3.472*10^8
Step-by-step explanation:
X-the $5 bills
y-the $10 bills
x+y=20
5x+10y=120
It's a system.
