Answer:
7x+14=0, 7x=-14, x= -2
Step-by-step explanation:
add like terms, then get x on one side, number on the other, then divide both sides by 7
2(6+w)+2(w)=40
12+2w+2w=40
12+4w=40
4w=28
w=7
Now we know that the width is 7; abd the length is 7+6 which is 13.
To find the area we multiply 13x7
The area is 92cm squared
Answer:
x = -3
Step-by-step explanation:
5 x + 3 = 4 x
Solve for x
5x - 4x + 3 = 0
x + 3 = 0
x = -3
The length is 30 meters and the width is 12 meters.
No, it is not correct.
First of all, you put the little 4 after the 8.
What you did in the equation is 8x4, not 8x8x8x8.
So, the correct answer to 8x8x8x8 would be 4096.
