Answer:
Problem 6: The product of two consecutive odd integers is equal to 675. Find the two integers.
Let x, x + 2 be the two integers. Their product is equak to 144
x (x + 2) = 675
Expand to obtain a quadratic equation.
x 2 + 2 x - 675 = 0
Solve for x to obtain two solutions
x = 25 or x = -27
if x = 25 then x + 2 = 27
if x = -27 then x + 2 = -25
We have two solutions. The two numbers are either
25 and 27
or
-27 and -25
Check that in both cases the product is equal to 675.

Step-by-step explanation:
A store sells a 9-ounce jar of mustard for $1.54. 1.54÷9 = $0.171
a 15-ounce jar for $2.55. 2.55 ÷ 15 = 0.17
I'd say they are proportional
Is the cost of the mustard proportional to the number of ounces for each jar? Explain.
Answer:
this is what I found "The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point. A bearing is used to represent the direction of one point relative to another point."
I can't really make sense of it though...
