Answer:
13x + 112 = 320.
Step-by-step explanation:
The perimeter is the sum of the 3 sides:
1/2 x + 3/8 x + 11 + 3/4 x + 3 = 40
1/2 x + 3/8 x + 3/4 x + 3 + 11 = 40
1/2 x + 3/8 x + 3/4 x + 14 = 40
Multiply through by 8 to remove the fractions:
4x + 3x + 6x + 14 = 40
13x + 112 = 320.
I'm pretty sure it is.
If i'm wrong, I'm truly sorry
Hello,
y=3x+b is parallele to y=3x-10
In order to determine b, we must know something else.
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
-15+2 means you add 2 to the negative number 15 so -15+2 will give us -13 which is the answer.
