Answer:
26 in
Step-by-step explanation:
Perimeter is calculated by adding all of the outside side lengths.
11 + 7 + 4 + 4 = 26
I assume you want the equation to be solved, so this is a quadratic simultaneous equation.
y = x^2-x-3 ——— (1)
y = -3x+5 ——— (2)
Sub (1) into (2)
(This is the first three steps provided)
x^2-x-3 = -3x+5
0 = x^2+2x-8
0 = (x-2)(x+4) ——— (3)
Solve for x in (3):
x-2 = 0
x = 2
x+4 = 0
x = -4
Sub x into (2)
y = -3(2) + 5
y = -1
y = -3(-4) + 5
y = 17
Hence the solution sets are:
x=2, y=-1
x=-4, y=17
Answer:
x^2 + 4x + 4
Step-by-step explanation:
Bc b^2 - 4ac = 0
The wholesale price for a bookcase is $151.
The markup is 37% of $151,

Therefore, the mark-up price is $55.87.
The price of the bookcase in the future store will be

Hence, the answer is $206.87.
I'll do it step by step:
3(x+2(3))=7(3)-9
3(x+6)=21-9
3x+18=12
I don't know what x is, so I think that's as much as I can do.
