Well we set the perimeter to 120 feet.
This means that 2x+2y=120
Now we know the area of a rectangle is xy so we have to solve for both x and y in the perimeter equation.
2x=120-2y
x=60-y
2y=120-2x
y=60-x
Now we plug these values into our area equation A=xy to get:
A=(60-y)(60-x)
Answer:
A. 8/10
Step-by-step explanation:
(0.8 × 10) / (1 × 10) = 8/10 (since, multiplying 10 shifts the decimal point towards the right by one place)
Further, we can reduce fractions 8/10 by dividing the numerator and denominator by 2.
(8 ÷ 2) / (10 ÷ 2) = 4/5
Thus, 0.8 as a fraction is 8/10 or 4/5
Answer: A, 7x^4 + x^3 – 3x^2 + 5x – 2
Step-by-step explanation: Standard form has the highest degree first, and goes down from there. A is the one that actually has the terms in the correct order
Hope this helps :)
Hello from MrBillDoesMath!
Answer:
56
Discussion:
See attachment.
As angle "a" + 93 = 180 (straight line has 180 degrees)
a = 180 -93 - 87
But a triangle also has 180 degrees so
37 + x + 87 = 180 =>
x = 180 - 87 - 37 = 56
Thank you,
