- The answer is A = x since the opposite sides of a rectangle are the same length.
- We'll have B = 9x+2 since this must add to x+4 to result in 10x+6. You could also do (10x+6) - (x+4) and you'll end up with 9x+2.
- On the far left side, (5x-3)+A = 5x-3+x = 6x-3. The far right side must add to this. So, x+C+x-2 = 6x-3 turns into C = 4x-1 after isolating C.
- Multiply out (5x-3) with (9x+2) to get the full area of 45x^2-17x-6. The steps are shown below
(5x-3)(9x+2)
5x(9x+2)-3(9x+2)
45x^2+10x-27x-6
45x^2-17x-6
You could also use the FOIL rule to get this answer. The box method is another alternative.
Answer:
Step-by-step explanation:
The given equation is:
5x+15 =0
Subtract 15 from both sides:
5x+15-15= 0-15
By solving the like terms we get:
5x=-15
Divide both sides by 5
5x/5 = -15/5
Simplify:
x= -3...
Answer:
90 ft³
Step-by-step explanation:
Volume is calculated as length × width × height.
Heidi: 5×3×2 = 30 ft³
Andres: 5×6×2 = 60 ft³
Total: 30 + 60 = 90 ft³
Value of x is -1
The correct first step to solving the inequality is distributing the -4 into the para thesis
