Answer:
1) 6 (9x - 5)
2) 4 (1 + 6)
Step-by-step explanation:
<u>1.</u>
54x - 30
The greatest common factor is 6, hence take out 6
6 (9x - 5)
<u>2.</u>
4 + 24
The greatest common factor is 4, take out 4
4 (1 + 6)
*I am not simplifying this because as per what is given, I am unsure if one of these numbers is actually a coefficient.
Answer:
infinite solutions
Step-by-step explanation:
y=5/2x+2
2y= 5x +4
Multiply the first equation by 2
y = 5/2 x +2
2y = 5/2 *2 x +2 *2
2y = 5x +4
Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
Answer:
b=-19
Step-by-step explanation:
We know that one of the solutions is x=-4/5
That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.
5(-4/5)^2+b(4/5)+12=0
Now, just solve for b.
5(16/25)+b(4/5)+12=0
(16/5)+(4/5)b+12=0
(76/5)+(4/5)b=0
(4/5)b=-(76/5)
b=-19
There are 6 sides to a hexagon and each side of the fence will be 6+2 = 8 feet
So you'll need 8*6 = 48 feet of fencing.
