Answer:
x=56
Step-by-step explanation:
I may be wrong but
That’s a pentagon so
5-2=3
180x3=540 ( total area of a pentagon)
89+99+72= 260
540-260=280
3+2=5
280/5=56
x=56
Answer:
20 minutes
Step-by-step explanation:
If he can run 3 miles in 30 minutes(half an hour) that means it takes him 10 minutes to run 1 mile. So to run 2 miles it would take him 20 minutes.
Answer:
I think its D)
Step-by-step explanation:
7x−3y+2=0
Add -7x to both sides.
7x−3y+2+−7x=0+−7x
−3y+2=−7x
Add -2 to both sides.
−3y+2+−2=−7x+−2
−3y=−7x−2
Divide both sides by -3.
−3y
/−3 = −7x−2
/−3
which equals d)
I also use this app to convert equations to slope-intercept and it showed me this
Answer:
Final factor is (x-9)(x+4)
Step-by-step explanation:
Given expression is
.
Now we need to factor that expression

Find two numbers whose product is -36 and sum is -5.
Two such numbers oare -9 and +4. So we get:



Hence final factor is (x-9)(x+4)
