Answer:
x=4
Step-by-step explanation:
Because 4 to the power of 2 is 16.
Then, you subtract: 16x - 7x
Then, what you are going to see is 9x=3x+24
So, you subtract: 9x - 3x
Finally, you will have 6x=24... You divide: 24/6 and the answer is x=4.
-4xy^6 * -3x = 12x^2y^6
-4xy^6 * 2y = -8xy^7
6 * -3x = -18x
6 * 2y = 12y
Answer = 12x^2y^6 + -8xy^7 + -18x + 12y
Answer:
The smallest is 14.
Step-by-step explanation:
Let the numbers be x, x+2 and x+4, then:
x + x + 2 + x + 4 = 48
3x + 6 = 48
3x = 42
x = 14.
So the 3 numbers are 14, 16 and 18.
Answer:
x = 10
Step-by-step explanation:
the area of a square = s² ( s is the side length )
s² = (4x + 3)² ( take the square root of both sides )
s = 
= 4x + 3
perimeter = 4s = 172, that is
4(4x + 3) = 172 ( distribute left side )
16x + 12 = 172 ( subtract 12 from both sides )
16x = 160 ( divide both sides by 16 )
x = 10
Answer:
MTTF for the fuses = 62.5
Step-by-step explanation:
Given:
Total fuses = 25
Number of failures = 12
Number of days = 30
Find:
MTTF for the fuses.
Computation:
MTTF for the fuses = Total operation time / Number of failures
MTTF for the fuses = (25 × 30) / 12
MTTF for the fuses = 62.5
