Step-by-step explanation:
A=(a+b)/2 h
A = (8+9)/2 * 13
A = 17/2 * 13
A = 110.5 inches

Answer:
x = - 8/23
y = 40/23
Step-by-step explanation:
-5x- y = 0
and
-8x+3y = 8
The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.
-5x-y = 0
-y = 5x
y = - 5x
Now you can take this y value and plug it into the section equation.
-8x + 3(-5x) = 8
-8x - 15x = 8
-23x = 8
x = - (8/23)
Once you get the x value you can plug it back into equation one to get y's value
-5*-(8/23) - y = 0
40/23 - y = 0
y = 40/23
Answer:
They do because y is always 4 times of x.

Step-by-step explanation:
cups
for sugar=1/4÷1/8=1/4×8=2
whole wheat flour=3/4÷1/8=3/4×8=6
all purpose flour=1/2÷1/8=1/2×8=4
If we know that two sets of corresponding angles and the corresponding included sides are congruent in two triangles, what can we say about the triangles?
