Answer:
Question A)
Question B)
Question C)
Step-by-step explanation:
A)
We are given:
We can rewrite the expression:
The square root and square will cancel each other out. Thus:
B)
We are given:
Rewrite:
Note that the square root of 9 is simply 3. We can also factor the second part:
Rewriting:
Simplify:
C)
We are given:
Rewrite. Note that 50 = 25(2):
Simplify. We can rewrite the factor as:
The square and square root will cancel out. Thus:
50 degrees celsius converted to fehranheit is 122 degrees
You can look at those dots, for example, you see (2,8) and (2,2) then look at y and the difference is 6. so if you see it like that, (2,8) and (5,8) is 3, (5,8) and (5,4) would be 4, (5,4) and (8,4) would be 3, (8,4) and (8,2) would be 2, and lastly (2,2) and (8,2) is 6
Now you add all of them up which will be 6+3+4+3+2+6 = 24
so the perimeter of this figure is 24<span />
I believe it’s 5,832,000
5^3 (5 times 5= 25 times 5= 125)^6(750 times 6= 4,500 etc)
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3
