Answer:
Step-by-step explanation:
x²+5x+6=x²+3x+2x+6=x(x+3)+2(x+3)=(x+3)(x+2)
so Volume=(x+3)(x+2)(x+4)
V=lwh
one of the factors is the length.
p=2w+2(6w-4) can be simplified to:
p=2w+12w-8
p=14w-8
if w=4
p=14(4)-8
p=56-8 = 48 yards
check:
w = 4
length = 6w-4= 6(4)-4 = 24-4=20
perimeter = 4*2 + 20*2 = 8+40 = 48
it checks out, perimeter = 48 yards
Answer:
x=2, y=3
Step-by-step explanation:
-7x-y=-17
7x-5y=-1
Add the two equations together to eliminate x
-7x-y=-17
7x-5y=-1
-------------------
-6y = -18
Divide by -6
-6y/-6 = -18/-6
y = 3
Now we need to find x
7x -5y = -1
7x -5(3) = -1
7x -15 = -1
Add 15 to each side
7x -15+15 = -1+15
7x = 14
Divide by 7
7x/7 = 14/7
x =2
Graph it so that the slope is 2
Step-by-step explanation:
The given is that John has 312ft of fencing. (Think of the 312ft as the perimeter)
The garden's legth is 6 ft more than 5 times it's width.
<em />
<em>Let </em><em>X </em><em>be the garden's width:</em>
<em />
This is what we know about the length:
It is 5 times + 6 more than the width
Now that we know this, lets set an equation to find the garden's dimentions.
X + (5X+6) = 312
(because we know Y = X * 5 + 6)
Now it's time to simplify:
Simplified X is equal to 51, so this is the length.
From the given the length is 5 times + 6 more than the width so the length is 5*51+6 which is 261
Answer:
The width is 51 and the length is 261. Hope this is correct and hope this helps. Brainliest would help :)
