Answer:
<em><u>Using the mid-term break formula for all of them.</u></em>
a) x²+7x+12
= x²+3x+4x+12
= x(x+3)+4(x+3)
= (x+4)(x+3)
b) x²+6x+8
= x²+2x+4x+8
= x(x+2)+4(x+2)
= (x+4)(x+2)
c) x²+5x+6
= x²+2x+3x+6
= x(x+2)+3(x+2)
= (x=3)(x+2)
d) x²+8x+7
= x²+7x+x+7
= x(x+7)+1(x+7)
= (x+1)(x+7)
Average = Mean
Mean → Add all the numbers and divide by how many there are
3 + 9 + 14 + 5 + 8 + 12 + 7 = 58
There are 7 numbers.
58 ÷ 7 = 8.3
Answer = 8.3
Hope this helped :)
Answer:
12
Step-by-step explanation:
Set x=0
when you do that, you will find the point where y=12 since x^2+8x=0, but adding the 12 moves up the y-component by 12 units
18 = x

5 4
x = 18•4 / 5
72/5 = 14.4 final answer
