So here is how you solve for the answer.
Firstly, you solve for the Area of Rectangle A.
The formula for Area is Length x width.
So A = (2x + 6)(3x) and the result is: 6x^2 + 18x
Now, let y be the width of rectangle B.
<span>(x+2) (y) = 6x^2 + 18x + 12
(x+2) y = 6(x+1)(x+2)
y = 6(x+1)
</span>So the final answer would be width is 6x + 6. The answer is the third option. Hope this answer helps.
Answer:
If he is traveling over 85 miles its cheaper to use company a
Step-by-step explanation:
137-65= 72
72÷0.85= 84.7058823529= 85
So after 85 miles company A is cheaper
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
Answer:
(x) =
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = ( multiply both sides by (x + 1)
y(x + 1) = x + 2 ← distribute left side
yx + y = x + 2 ( subtract x from both sides )
yx - x + y = 2 ( subtract y from both sides )
yx - x = 2 - y ← factor out x on the left side
x(y - 1) = 2 - y ← divide both sides by (y - 1 )
x =
Change y back into terms of x, thus
(x) =
Answer:
-20
Step-by-step explanation:
f (-3) = 12 x -3 + 11 +5
^
12 x -3 + 16
^
-36 + 16
^
= -20
