The answer would be the one with the check mark right
Answer:
3
Step-by-step explanation:
You substitute the 3, 2 and 7 in for your variables (the letters) and add parentheses ( ) to organize your data and use order of operations (PEDMAS) to solve. So when I did it I but the numbers in (3*3) + (11*2) - (4*7), then solved inside the parentheses to get 9 + 22 - 28 and solved across, 9 + 22 = 31 - 28 = 3. Hope this made sense and helps!
Answer:
line one should have a y-intercept at (0,2).
Step-by-step explanation:
A = L * W
A = 45
L = 2W + 1
45 = W(2W + 1)
45 = 2W^2 + W
2W^2 + W - 45 = 0
(2W - 9)(W + 5) = 0
W + 5 = 0
W = -5...not this one because it is negative
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <=== the width is 4.5 ft
L = 2W + 1
L = 2(4.5) + 1
L = 9 + 1
L = 10 <=== the length is 10 ft
