Answer:
width: 8.5
length: 4
Step-by-step explanation:
width: x
length: 2x - 13
area = length * width
34 = (2x - 13)x
34 = 2x² - 13x
2x² - 13x - 34 = 0
(2x - 17)(x + 2) = 0
2x - 17 = 0
2x = 17
x = 8.5
x + 2 = 0
x = -2 width cannot be negative so discard this
width: x = 8.5
length: 2x - 13 = 2(8.5) - 13 = 4
Your answer is D. y = 36
We can find this by just rearranging the equation firstly:
2 + √4y - 3 = 11
√4y - 1 = 11
√4y = 12
Now we can simplify √4y, because 4 2², so you get 2√y :
2√y = 12
√y = 6
We can now square both sides to get the equation as "y ="
y = 36
I hope this helps! Let me know if you have any questions :)
Answer:
if this is graph if its not tell me but this is my answer for graph? 1: Xmin:-10
Xmax:10
Ymin:-10
Ymax: 10
2: Xmin:-10
Xmax:10
Ymin:-10
Ymax:10
Step-by-step explanation:
The answer is
B
The answer must have a positive twenty so you can rule out A and C.
That leaves us with D
D has just 6x. The x has to be 3x times 4 and 6x times 5, which comes out to 42x, proving D wrong and leaving you with B
You would use -3 so the top equation would be
-3x-3y=-12
3x+4y=14
