Answer:
10^9
Step-by-step explanation:
1,000,000,000
There are 9 zeros
This is in the form
a* 10^b where a is the first digit and b is the number of zeros
1 *10^9
We can drop the 1 because 1 times anything itself
10^9
Answer:
x = -10
Step-by-step explanation:
Combine like terms and solve for x
3x + 8 = x - 12
3x= x - 20
2x = -20
x = -10
Let's say x is "number"
14) 2x-5=7
16) 6x-6=12
18) 2x+7=1
20) 8(n-3) or 8(3-n)
19) 9 + x/7=11
21) The product of 2 and the sum of 5 and t is 8
Hope this helped : )
Length = 5x
width = x
area = 125
A = L*W
125 = (5x)(x)
125 = 5x^2
125/5 = x^2
25 = x^2
sqrt{25} = sqrt{x^2}
5 = x
The width is 5 feet.
The length is 5 times 5 feet or 25 feet.
To find the perimeter, we use P = 2L + 2W.
P = 2(25) + 2(5)
P = 50 + 10
P = 60 feet.
Done!
