Answer:
(a + 4)(a + 6)
Step-by-step explanation:
f(a) = a² + 10a + 24
I think you are asking us to factor the quadratic.
1. Multiply the leading coefficient and the constant
1 × 24 = 24
2. Find two numbers that multiply to give 24 and add to give 10.
Possible pairs are 1, 24; 2, 12; 3, 8; 4, 6
Start with the numbers near the end of the list.
By trial and error, you will find that 4 and 6 work:
4 × 6 = 24 and 4 + 6 = 10
3. Rewrite 10a as 4a + 6a
a² +4a + 6a +24
4. Factor by grouping the first two and the last two terms
a(a + 4) + 6(a + 4)
5. Distribute the a + 4
(a + 4)(a + 6)
a² + 10a + 24 = (a + 4)(a + 6)
Answer:
x = -1
y = -5
Step-by-step explanation:
9(2y+9) - 8y = 31
18y + 81 - 8y = 31
10y + 81 = 31
10y = -50
y = -5
2(-5) + 9 = x
-10 + 9 = x
-1 = x
The square root is an inverse mathematical operation of a square. The square root of 125 is the value that is obtained after taking the square root of 125. The simplified radical form of square root of 125 is 5 √5.
-7p=-2-6p
7p=2+6p
p=2
Hope this helps :)
It is either A or B. I'm not sure which one.
