Answer:
he needs to know the width!!!
Step-by-step explanation:
since length multiplied by the width equals area,
so since the length is given, the width is needed
Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
Answer:
20*6 - 120
20*6 = 120
19 * 6 = 114
Step-by-step explanation:
Call x the scale factor.
20x + 19x + 20x = 354 Add the left side together.
59x = 354 Divide by 59
59x/59 = 354/59 Combine and cancel
x = 6
The lengths of the sides are
20 * 6 = 120
19 * 6 = 114
20 * 6 = <u>120</u>
Total 354 Check
Answer:
(4, 2)
Step-by-step explanation:
y = 2x^2 - 16x +34 can be simplified by factoring out 2 from all three terms on the right side: y = 2(x^2 - 8x + 17).
We need to "complete the square" here. Notice that the coefficient of x is -8; we take half of that (which is -4) and square this result (which yields 16).
Focusing on x^2 - 8x + 17, we add 16, and then subtract 16, obtaining:
x^2 - 8x + 16 - 16 + 17, or (x - 4)^2 + 1
Now return to the original function, y = 2(x^2 - 8x + 17).
Replace x^2 - 8x + 17 with [x - 4]^2 + 1:
We get y = 2(x^2 - 8x + 17). = 2( [x - 4]^2 + 1 )
This has the form y = a(x - h)^2 + k, and by comparison we see that h = 4 and k = 2. The vertex of this parabola is at (4, 2).
