Answer:
-24
Step-by-step explanation:
For this question, all you have to do is multiply the number outside the bracket by the number inside the bracket.
12 x -2
The law of negatives says that when you multiply a positive number by a negative number, the answer will be negative
∴ the answer will be negative
all that's left now is to multiply 12 by 2
12 x 2 = 24 (remember the answer will be negative)
answer: -24
I HOPE THIS WAS HELPFUL :-)
Answer:
the answer is 3since x is 2 so it becomes 5times 2 minus 7 equals to 3
Let x be the width of the sidewalk and the area becomes:
A=LW and L=6+2x and W=4+2x now we have
A=(6+2x)(4+2x) and we are told that A=48ft^2
48=24+20x+4x^2
4x^2+20x-24=0
4(x^2+5x-6)=0
x^2+5x-6=0
x^2-x+6x-6=0
x(x-1)+6(x-1)=0
(x+6)(x-1)=0
So x=-6, 1, however since x is a measurement it must be positive thus
x=width=1 ft is the only possible solution.

Answer:
1/2, 5/2
Step-by-step explanation:
Rearrange the system of equations.
-3x + y = -1
x + y = 3
Multiply the bottom equation by 3
3x + 3y = 9
Now add the two equations
4y = 10
y = 5/2
Now plug y back in to solve for x in one equation
x + y = 3
x + 5/2 = 3
x = 1/2
Answer in coordinates: 1/2, 5/2
