Answer:
22
Step-by-step explanation:
Pretend the 10 values in the first sentence are a,b,c,d,e,f,g,h,i,j
Pretend the addition 5 values is k,l,m,n,o
So the mean of all the 15 data is (a+b+c+d+e+f+g+h+i+j+k+l+m+n+o)/15=20
So the sum of all 15 data is a+b+c+d+e+f+g+h+i+j+k+l+m+n+o=300 since 15(20)=300
Now let's look at the first 10: We have their mean so we can write:
(a+b+c+d+e+f+g+h+i+j)/10=19
so a+b+c+d+e+f+g+h+i+j=190 since 10(19)=190
So that means using our first sum equation and our equation sum equation we have
190+k+l+m+n+o=300
k+l+m+n+o=300-190
k+l+m+n+o= 110
So the average of those 5 numbers mentioned in your problem is 110/5=22
Answer:
3
Step-by-step explanation:
The answer is 3 because the blue line goes across the y - axis at 3.

The given trinomial can be factored using the factorization method.
x² + 15x + 56
= x² +8x +7x + 56
= x(x+8) + 7(x+8)
= (x+8)(x+7)
Thus, (x+8)(x+7) is the factored form of the polynomial.
So the correct answer is option B
(y + 7)(y + 7)
49 is a perfect square of 7
it can also be written
(y + 7)²
hope this helps :)
