90-69=21 degrees. This is our target answer. We'll write an equation to do this:
2x-1=21
Add 1 to each side to get:
2x=22
Divide by 2 to get that x=11
Plugging this in, we see that 2(11)-1+69=90, so our answer is correct.

Solution:
Consider numbers which are Squares,cubes, fourths, fifths of some natural numbers.
For example, Starting from squares of some natural number: 4,9,16,25,36,49,64......
and their factors , which are 4= 1 × 2×1×2
9=1×3×1×3
16=2×1×2×1×2×1×2×1
25=1×5×1×5
36=2×3×2×3
64=2×4×2×4
Now coming to cubic numbers
8= 1 ×2×1×2×1×2
27= 1×3×1×3×1×3
3125= 3 ×5×3×5×3×5
So,the numbers whose factor pairs repeats are square, cubic, fourth,Fifth ,Sixth and.....higher powers of natural Numbers.
→→→So, we just need to check that whether those numbers whose factor pairs repeats are Squares, cubes or higher powers of natural numbers.
Answer:
36 hours
Step-by-step explanation:
since it's two people if they work separately it would take twice as long therefore 18 multiplied by 2
Answer:
Mean is 9
Median is 6
Step-by-step explanation:
Mean is the average and the median is the middle of the numbers in order:)
In the equation of a straight line(when the equation is written as "y=mx+b), the slope is the "m" that is mutiplied on the x and the b is the y intercept where the line crosses the y axis
