Answer:
Total number of ways will be 20
Step-by-step explanation:
We have given three identical green shirts and three identical red shirts
So total number of shirts = 3+3 = 5
We have to distribute these shirts to 6 children so that each children got one shirt
Number of ways will be equal to 
( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )
I believe the 3rd answer down if the information you provided is correct
Squaring the sum on the top, rules out 1 and 2 (not squaring the 7 only)
then 4 times the difference. so I believe 4 (x-1) on the bottom.
Answer: x^5+5x^4+x^3
Step-by-step explanation:
assuming the expression is x^3(x^2+5x+1) each term in the bracket is multiplied by x^3
x^3(x^2+5x+1)
=(x^3*x^2)+(x^3*5x)+(x^3*1)
=x5+5x^4+x^3
Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
14 10/8 is equal to 15 2/8 which cnman simplify down to 15 1/4. So, the simplest you can get is 15 1/4. I hope this helps!
