Answer:
5unit
Step-by-step explanation: since area of rectangle = length*width
Here length is (x+2) and width is(2x+3)
(x+2)(2x+3)=91
On further solving
2x^2+75x-85=0
2x^2-10x+17x-85=0
2x(x-5)+17(x-5)=0
(2x+17)(x-5)=0
x=5unit
Answer:
your right
Step-by-step explanation:
you had it right nothing to do
6x2=12
12x4=48
This seems to obvious, so it may be wrong!
Answer:
C. ![y=\sqrt[3]{-x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D%20-1)
Step-by-step explanation:
Consider the eparent function
The graph of this function is shown in the attached diagram - red curve.
Reflect this graph across the y-axis, you'll get the blue line which equation is
![y=\sqrt[3]{-x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D)
Translate this graph 1 unit down, then you'll get green line (that is exactly the graph from your image) and the function for this line is
![y=\sqrt[3]{-x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D%20-1)
X=22
Area is found by multiplying (x+7)and (2x-1) together. 22+7=29, 2(22) -1 = 43, 43+29=72
