U need to find the length
7 + 7 + 18 + 18 = 50
width is 7 and length is 18
area is length x width
18 x 7 = 126 ft^2
He can receive 8 months of internet.
He has $134, and the initial fee is 30. Subtract 30 from 134. This gives you 104. Next, divide by the monthly fee of $13. 104/13=8
The answer is 1561 yuans and 27 jiao.
Answer:
Step-by-step explanation:
x^2 + 4x = 15.....take half of ur x term, then square it, then add to both sides
x^2 + 4x + 4 = 15 + 4
(x + 2)^2 = 19
sqrt (x + 2)^2 = sqrt 19
x + 2 = sqrt 19
x = -2 (+ - ) sqrt 19
so x = -2 + sqrt 19 or x = -2 - sqrt 19
Answer:
The given equation 3x − 7 = 4 + 6 + 4x has one solution.
Step-by-step explanation:
Given : Equation 3x − 7 = 4 + 6 + 4x
We have to find the number of solutions of the given equation.
Consider the given equation 3x − 7 = 4 + 6 + 4x
Simplify, we have,
3x − 7 = 10 + 4x
Now subtract 3x both side, we hvae,
-7 = 10 + 4x - 3x
Simplify, we have,
- 7 = 10 + x
Subtract 10 both side, we have,
-7 - 10 = x
x = - 17
Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.
