The sum of two numbers is 85. There difference is 9. Find the numbers
2 answers:
Represent the numbers as expressions.
number 1 - n
number 2 - n + 9
Isolate “n.”
n + n + 9 = 85
2n + 9 = 85
2n = 85 - 9
n = 76/2
n = 38
Determine the numbers by substituting the n value into the expressions.
1. n = 38
2. n + 9 = 38 + 9 = 47
Therefore the numbers are 38 and 47.
Answer:
38 and 47
Step-by-step explanation:
The first number would be = (85-9)/2
= 76/2 = 38
The second number would be either 85 - 38 or 38 + 9 = 47

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)
