Answer:
That's true
Step-by-step explanation:
First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
The answer is b
first do x+1, which is 4
then do 4(4), which is 16
then add the 3 to 16, which is 19, thus b is correct
Answer:
150
Step-by-step explanation:
A=B*H/2
A=15*20/2
A=300/2
