The answer should be 61
4×3=12
7×7=49
12+49=61
4×3 + (7×7)
L=17.49635531
W=5.715476066
100 = L X W
L = 2+ 3W
Insert the L equation into the 1st equation, 2+ 3W x W = 100
<span>2+ 3W x W = 100
</span>-2 -2
3W X W = 98
3W^2 = 98
Divide both sides by 3
W^2 = 32.66
Square root both sides
now you have the Width, plug the width into the L X W = 100 equation, then divide 100 by the width, and now you have the length.
Answer:
5/2 x^2y^2
Step-by-step explanation:
( x^2 - 3/5y^2)^2 + (3/4 x^2 + 4/5 y^2)^2 - (5/4x^2 - y^2)^2
= x^4 - 6/5x^2y^2 + 9/25y^4 + 9/16x^4 + 6/5x^2y^2 + 16/25y^4 - ( 25/16x^4
- 5/2x^2y^2 + y^4)
Distributing the negative over the parentheses:-
= x^4 - 6/5x^2y^2 + 9/25y^4 + 9/16x^4 + 6/5x^2y^2 + 16/25y^4
- 25/16x^4
+ 5/2x^2y^2 - y^4
Bringing like terms together
x^4 + 9/16x^4 - 25/16x^4 - 6/5x^2y^2 + 6/5x^2y^2 + 5/2x^2y^2 + 16/25y^4 + 9/25y^4
- y^4
Adding like terms:-
= 5/2 x^2y^2 Answer
Answer:
D
Step-by-step explanation:
3/5 = 0.6
75% = .75
0.8, 0.75, 0.6, 0.56
You will have to factor 6c out of 42c2+24c. Then the answer will be 6c(7c+4).
