Answer:
525 ft sq.
Step-by-step explanation:
Variable.
Length = 2w+5
Width = w
2(l+w)=100
2(2w+5+w)=100
2(3w+5)=100
6w+10=100
w=15
l=35
15*35=525
9514 1404 393
Answer:
(x, y) = (12, -12)
Step-by-step explanation:
The two equations can be added to solve for x.
(-5x -5y) +(6x +5y) = (0) +(12)
x = 12 . . . . . . . . simplify
-5(12) -5(y) = 0 . . . substitute into the first equation
12 +y = 0 . . . . . . . divide by -5
y = -12 . . . . . . . . subtract 12
The solution is (x, y) = (12, -12).
SO do the one in the paranthesis first.
First we need to add the paranthesis. Which we will get 3.
3*2 ( because multiply goes first). Then divide the number 6 with the conclusion of 1. Then as we add and subtract 1, we will get the answer 1!
Answer : 1!
You just put the fractions where they say they are supposed to be, so put 7/4 in for y and put 7/6 in for x. Then, you have to first do the exponent since it comes first in PEMDAS, so after that you solve the exponent, you get -343/-216. Next, you have to do 7/4- 343/-216. After that you get the fraction 35/216.
