Answer:
the x should be 10x7-(9x6)
Step-by-step explanation:
because it should be 10x7-(4+30)
D) 1•x=5, 1•5=5 8•5=40, the answer is 40/5 CDs
E) 3/3=1, 26.25/3= 8.75. The answer is 1/8.75
F) 10/10=1, 120/10= 12. The answer is 1/12
G) 2•x=12, 2•6=12, 120•6= 720. The answer is 12/720

Answer:
120ft and 240ft
Step-by-step explanation:
720 = 2L + 2W
Since L = 2W, we get
720 = 2(2W) + 2W
6W = 720
W = 120
L = 2W = 2(120) = 240
The dimensions of the yard are 120 feet and 240 feet
The answer is 22/5
You multiply 5 and 4, which you get twenty, then you add 2 and you get 22. Divide that by 5, and you get 22/5.
To double check, divide 22 by five and you should get 4.4, or 4 2/5 as a fraction
We have the following expression:
(2x + 5) * (7-4x)
Rewriting we have:
14x - 8x ^ 2 + 35 - 20x
Grouping terms with the same exponent:
-8x ^ 2 + x (14-20) + 35
Rewriting:
-8x ^ 2 - 6x + 35
Answer:
the quadratic expression for this is:
-8x ^ 2 - 6x + 35
