the missing number should be the square root of the last number times 2 for a perfect trinomial
so square root of 49 = 7
7*2 =14
so the missing number should be 14
Answer:
Yes! You can
Step-by-step explanation:
1. If this is rows and columns it is doable, however if you are speaking columns by rows it isn't
2. You multiply them like normal except when you reach the end on your 2x2 matrix you repeat the cycle

Answer:
the number of boys and girls on a team is 58 and 26 respectively
Step-by-step explanation:
Given that
Total members in swimming team is 84
Let us assume the number of girls be x
so, the number of boys would be
y = 2x + 6
Now the equation is
x + y = 84
x + 2x + 6 = 84
3x = 78
x = 26
And, y = 2 × 26 + 6
= 52 + 6
= 58
Hence, the number of boys and girls on a team is 58 and 26 respectively
<span>f(x) = 2x + 3
</span><span>g(x) = x²-7
</span>(f+g)(x) = f(x) + g(x) = 2x + 3 + x² - 7 = x² + 2x - 4
(f+g)(x) = x² + 2x - 4
14.23 is your answer!!!!!!!
