Answer:
88 ft^2
Step-by-step explanation:
To find the surface area of a rectangular figure
SA = 2(lw+lh+hw)
where l=length, w= width, h = height
let l=6, h=2, w=4
SA = 2(lw+lh+hw)
= 2 (6*4+ 6*2+ 2*4)
=2 (24+12+8)
=2 (44)
= 88
SA = 88 ft^2
Answer:
Option B
Step-by-step explanation:
8 - 2x < 18
Subtract 8 from both sides;
-2x < 10
Divide both sides by -2
x > -5
Answer:
3w - 9/2 is the equivalent expression

Answer:
The graph of image and preimgae is shown below.
Step-by-step explanation:
From the given figure it is noticed that the vertices are A(-2,2), B(5,2), C(5,0), D(0,0), F(0,-2) and G(-2,-2).
It is given that figure ABCDFG is rotated by positive 90° about the origin (0,0).
Positive means counter clockwise and negative means clockwise.
If a figure is rotated by counter clockwise 90° about the origin (0,0), then
![(x,y)\rightarrow (-y,x)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28-y%2Cx%29)
The vertices of image are
![A(-2,2)\rightarrow A'(-2,-2)](https://tex.z-dn.net/?f=A%28-2%2C2%29%5Crightarrow%20A%27%28-2%2C-2%29)
![B(5,2)\rightarrow B'(-2,5)](https://tex.z-dn.net/?f=B%285%2C2%29%5Crightarrow%20B%27%28-2%2C5%29)
![C(5,0)\rightarrow C'(0,5)](https://tex.z-dn.net/?f=C%285%2C0%29%5Crightarrow%20C%27%280%2C5%29)
![D(0,0)\rightarrow D'(0,0)](https://tex.z-dn.net/?f=D%280%2C0%29%5Crightarrow%20D%27%280%2C0%29)
![F(0,-2)\rightarrow F'(2,0)](https://tex.z-dn.net/?f=F%280%2C-2%29%5Crightarrow%20F%27%282%2C0%29)
![G(-2,-2)\rightarrow (2,-2)](https://tex.z-dn.net/?f=G%28-2%2C-2%29%5Crightarrow%20%282%2C-2%29)
