4 because it has four sides
Answer:
Step 1. Should be 3(x +2x) -2(x +1) +5 . . .
or . . . 3x(1 +2) -2(x +1) +5 . . .
or . . . 9x -2(x+1) +5
Step-by-step explanation:
Lisa apparently failed to realize that both terms inside the first set of parentheses have 3x as a factor. They are like terms, so could be combined directly. If Lisa really wants to factor out 3 or 3x, she could do so and then combine the remaining factors at another step.
B=x-5
To get x on its own you have to add 5 to both sides. This gives you:
b+5=x
or
x=b+5
Answer:
A, is the answer.
Step-by-step explanation:
If you take two points and then find the slope between them you'll find that it is 1.5.
You could also make a T-chart or plug in the x coordinates into each possible equation and see which one matches the corresponding y coordinate.
