Answer:
16
Step-by-step explanation:
Substitute 3 for n,
6(3) - 2
then multiply
18 - 2
then subtract
16
B. You have to solve for X, and graph using whatever is less than or greater than. 4x + 12 < 4 to 4x < -8 to x < -2.
The formula for the area of a square is A=s*s or A=s^2
So we can plug in the area and solve for the side
576=s^2 (square root both sides)
s=24 inches
Since one foot is 12 inches, 24 inches would be 2 feet
Hope this helps
Answer:
7 is about 6 because it says to round to the nearest whole number
Step-by-step explanation:
8 is about 3 because it say to round to the nearest whole number
The answer to this is 65.
Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.
First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.
Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65
