Answer:
Step-by-step explanation:
Area of the rectangle = 33 inches sq
Area of a rectangle (formula) = l*b
let the width be x
length = 2 inches + 3x = 2+3x
Area of the rectangle = l*b = 2+3x + x
33 inches sq = 2+3x + x
33 in sq = 2+4x
33/2 = 4x
16.5/4 = x
x = 4.125
width= <u>4.125 inches</u>
length = 2+3x = 2+3(4.125) = <u>14.375</u>
<u></u>
(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
435 inches = 36 1/4 ft.
So, the answer would be D) 12 ft. 3 in. hope this helps
There are no coordinates for an equation like this, you have to just graph the problem. Just try graphing something similar to this (or just include this image). Hope this helps!
<u>Answer:
</u>
f(x) = 3(x+2)(x-2)
<u>Step-by-step explanation:
</u>
We are given the following the quadratic function and we are to rewrite it in intercept or factored form:
We can factorize the given function so taking the common factors out of it to get:
The term 
is in the form 
so it can further be factorized to give:
Therefore, the factored form of the given quadratic function is f(x) = 3(x+2)(x-2).
Answer:
7
Step-by-step explanation:
We have that x1=−1, y1=5, x2=3, y2=7.
Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(12)(−1)=112
Finally, the equation of the line can be written in the form y=b+mx:
y=112+x2
