Answer:
D
Step-by-step explanation:
I'm assuming you're looking for area here.
The formula is b * h = A
So all you're doing is multiplying 30 by 18 to get 540.
Answer:
First one is a slope between 0 and 1
second one is a slope lower than 0
third one is a slop higher than 1
last one is a slope higher than 1 (technically undefined)
Step-by-step explanation:
The slopes of two parallel lines must be identical.
We have slope

, so the slope for the parallel line be the same.
Now, to find an equation that also passes through the given point, we use slope-point form,

, where our point

is substituted for

.

Now, we convert to slope-intercept form as such.

And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.
3²×7................................................
Answer:
7
Step-by-step explanation:
12b -b = 11b
11b = 77
Divide both sides by 11
b = 7
