P = 2(l + w)
w = l/2
Plug in 'l/2' for 'w' in the equation with '66':
66 = 2(l + l/2)
66 = 2l + 2l/2
66 = 2l + l
66 = 3l
22 = l
So the length is 22.
Now plug this in to find the width.
66 = 2(22 + w)
66 = 44 + 2w
22 = 2w
11 = w
So the width is 11, and the length is 22.
Answer:
2a times the sq root of 2a or 2a (2a)**1/2
Step-by-step explanation:
(8a**3)**1/2 =
((2**2 * 2) (a**2) (a))**1/2 then take out and squares
2a (2a)**1/2
or 2a times the sq root of 2a
Answer: B, D, E
Step-by-step explanation:
Statement 1 cannot be true because f(1)<0.
Statement 2 might be true.
Statement 3 cannot be true because if f is continuous, then for some value between -1 and 0, f(x) is positive by the Intermediate Value Theorem.
Statement 4 might be true.
Statement 5 might be true
Slope 2, y int -7
In y = mx + b form, the slope is in the m position and the y int is in the b position. So it is just a matter of subbing
y = mx + b
y = 2x + (-7).....not quite done..distribute thru the parenthesis
y = 2x - 7
1:B
