The area is 128
multiply the base by the height, and then divide by 2.
the base is 16 and the height is also 16 so 16x16 is 256 divided by 2 is 128
So you can’t factor out the variables since one is d and the other is a. If they were the same letter you could factor them out as well
The only number that goes into both 9 and 12 is three
So divide by three essentially and take it out and place is next to the rest of the equation that is now in parenthesis
3(3d^3 - 4a^2)
The ones that apply are x-2 and x+3 as these are the factors of x2 - x - 6
Answer:
3x8= 24sf
5x7= 35sf
9x10= 90sf
13x2= 26sf
8x8= 64sf
Step-by-step explanation:
Note that the whole number 1 = 20/20
As 20/20 = 1
There are 4 whole numbers. multiply the numerator by 4
(20/20) x (4/1) = 80/20
Next, add the improper fraction gotten to the fraction given, 12/20
80/20 + 12/20 = 92/20
92/20 is your improper fraction, or 23/5 (simplified)
hope this helps
