To calculate area of a Square you'll take a side and square it for example
48ft of fence
48/4=12
Now you'll square
12ft^2
I hope this works...
Answer:
6
Step-by-step explanation:
Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.
The answer is 24+30
6x4=24
6x5=30
(D)
(3x2 + 7y) (2x2 – 3x + 9)
=(6+7y)(-3x+13)
=-18x+78-21xy+91y
