AB + CD = BC + DA
<span>Where A, B, C, and D are points on the quad, and AB is the length of the line A to B, etc. </span>
<span>Since you know three sides, you can easily solve for the fourth. </span>
-10a and -8a are like terms, but -3ab is not equivalent. With the two a terms, we have:
-10a-8a
a(-10-8)
-18a
We then add in the other term (-3ab) for a final result of -3ab+-18a. This can be factored alternatively as -3a(b+6).
Answer: 5 m
Step-by-step explanation:
Double the area to get 35. then think what two number multiply to get 35 that are also 2 apart. 7 x 5. So 7 is the height and 5 is the base.
Check answer: A = 1/2xbxh
A = 1/2 x 7 x 5
A = 1/2 x 35
A = 17.5 sq m
The first thing you want to do is factor out 13. It can ether be (1, 12), (2, 11), (3, 10), (4, 9), (5, 8), or (6, 7). In this case, it says the difference of the two numbers is 3, so you subtract the two numbers 8 and 5 to get three. Your answer is 8 and 5
