Answer:
<em>13.1</em>
Step-by-step explanation:
A = bh
~~~~~~~
= 16 ,
= 9
A = 16 × 9 = 144
From another side area of parallelogram with hight "h" base "b"
11h = 144
<em>h</em> = 144 ÷ 11 ≈ <em>13.1</em>
A=2(wh+lw+lh)
l=8m
w=3m
h=2m
A=2((3m)(2m)+(8m)(3m)+(8m)(2m))
A=2((6m)+(24m)+(16m))
A=2(46m)
A=92m
Area is 92m
So you will need to solve for x and y before evaluating 2x+y....
2x-y=9, y=2x-9 now this will make 4x^2-y^2=171 become:
4x^2-(2x-9)^2=171
4x^2-(4x^2-36x+81)=171
36x-81=171
36x=252
x=7, now we can use 2x-y=9 to solve for y...
2(7)-y=9
14-y=9
-y=-5
y=5
now we know that x=7 and y=5, 2x+y becomes:
2(7)+5
14+5
19
Answer:
240 cubic centimetres
Step-by-step explanation:
volume of the right rectangular prism

Answer:
see below
Step-by-step explanation:
We want where both inequalities are true
y > -3
-2 >-3 this is true
y ≥ 2/3x -4
-2≥ 2/3*3 -4
-2 ≥ 2 -4
-2≥ -2
This is true
This is is the graph
