Answer:
x = -10
Step-by-step explanation:
Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.
4(x+5) = 3(x-2) -2(x+2)
4x + 20 = 3x - 6 - 2x - 4
4x + 20 = x - 10
3x = -30
x = -10
Expanding the given expressions using Foil:
1)(–7x + 4)(–7x + 4) =
2) (–7x + 4)(4 – 7x)=
3)(–7x + 4)(–7x – 4)==
4)(–7x + 4)(7x – 4)=
The third option that is (–7x + 4)(–7x – 4) is difference of two squares.
The answer is undefined
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
Answer:
B. 11i-4j+2k
Step-by-step explanation:
Answer:
D. Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2
Step-by-step explanation:
Key goal is to have x on one side while the other value to the right. By subtracting 14x on both sides, you would get x+6=5. You would finally subtract 6 on both sides, not 5, to get the x by itself, thus x=-1.
