Answer:
1.a
2.d
Step-by-step explanation:
1. find the opposite the negative version of the number is the right one (a)
2. (7+x)(8) = 56+8x [d]
7 + x is the the expression
8 is the length
find the area you multiply
Answer:

See Attachment for Graph
Step-by-step explanation:
Given


Required
Determine the point of intersection
To do this, we simply equate both expressions of y
i.e.

Solve for x


Divide through by -5



<em>Hence, the point of intersection is 1.2</em>
I have the answer in this picture. But im not sure if this might be really what your asking for.
Answer: x=-6
Step-by-step explanation:
Given
2x + 8 = -4
Subtract 8 on both sides
2x + 8 - 8 = -4 - 8
2x = -12
Divide 2 on both sides
2x / 2 = -12 / 2
x = -6
NOTE: I assume the questions "solve for c" actually means "solve for x"
Hope this helps!! :)

Answer:
x = 1
Step-by-step explanation:
We need to solve for x by isolating the variable.
First, expand the parentheses:
2(x + 1) = 4
2 * x + 2 * 1 = 4
2x + 2 = 4
Then subtract by 2:
2x + 2 - 2 = 4 - 2
2x = 2
Finally, divide by 2:
2x/2 = 2/2
x = 1
Thus, x = 1.
Hope this helps!
