Answer:
Numbers are 5 , 7
Step-by-step explanation:
<h2>
Forming quadratic equation and solving:</h2>
Let the two consecutive odd numbers be (2x + 1) and (2x + 3)
Their product = 35
(2x + 1)(2x + 3) = 35
Use FOIL method.
2x*2x + 2x*3 + 1*2x + 1*3 = 35
4x² + 6x + 2x + 3 = 35
Combine like terms
4x² + 8x + 3 = 35
4x² + 8x + 3 - 35 = 0
4x² + 8x - 32 = 0
<h3>Quadratic equation: 4x² + 8x - 32 = 0</h3>
<u>Solving:</u>
4x² + 8x - 32 = 0
Divide the entire equation by 2
2x² + 4x - 16 = 0
Sum = 4
Product = -32
Factors = 8 , (-4)
When we multiply 8*(-4) = -32 and when we add 8 + (-4) = 4.
Rewrite the middle term
2x² + 8x - 4x - 16 = 0
2x(x + 4) - 4(x + 4) = 0
(x + 4) (2x - 4) = 0
2x - 4 = 0 {Ignore x +4 = 0 as it gives negative number}
2x = 4
x = 4/2
x= 2
2x + 1 = 2*2 + 1 = 5
2x + 3 = 2*2 +3 = 7
The numbers are 5 , 7
Answer:

Answer:
Leah's unit rate is 16 problems per minute.
Step-by-step explanation:
To find her unit rate, we need to find how many problems she can do in 1 minute. Our current fraction is . We need to divide the top and bottom by 2.5 to get the rate per minute
=
Leah's unit rate is 16 problems per minute.
