So it's really easy to do this
4 times 2 is 12 and then time 10 degree
=12 times 10 degree
=120 degree
As long any understand that you don't have to change or do anything with the degree and just multiply the numbers .
I hope it helped u

Free points?!?
Step-by-step explanation:
Answer:
Simon: 55 hours
Alvin: 70 hours
Theodore: <u>159</u> hours
Total: 284 hours
Step-by-step explanation:
Let A, T, and S stand for the hours worked by Alvin, Simon, and Theodore.
We are told that:
A = S + 15,
T = 3S - 6
and
A + S + T = 284
Note that the first two equations state the value of A and T in terms of S. Let's use them in the third equation, so that we'll have only one unknow:
A + S + T = 284
(S + 15) + S + (3S - 6) = 284
5S + 9 = 284
<em><u>S = 55</u></em>
Now use this value of S in the first two equations to find A and T:
A = S + 15
A = 55 + 15
<u><em>A = 70</em></u>
T = 3S - 6
T = 3*55 - 6
<em><u>T = 159</u></em>
<u></u>
<u>(55 + 70 + 159) = 284</u>
<u></u>
Answer:
C) To square a number, multiply the number by itself.
Step-by-step explanation:
A) is incorrect because square roots are made by multiplying the number to itself.
2 × 2 is the same as 2²
3 × 3 is the same as 3²
4 × 4 is the same as 4²
2² = 4
3² = 9
4² = 16
B) is incorrect because the inverse of squaring is finding the square root.
2² inverse is √4
3² inverse is √9
4² inverse is √16
D) is incorrect because perfect squares can be odd or even
A perfect square is a number made by squaring a whole number.
4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
