Can someone please solve this problem for me?
statuscvo [17]

Answer:

5 and 7.

Step-by-step explanation:

Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:

*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.

x *(x+2)=35

Expanding, you get:

x^{2}+2x = 35.

And moving the 35 to the other side, you get a simple quadratic.

x^{2}+2x -35 =0.

Solving by factoring:

(x+7)(x-5)

This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).

A rectangular picture frame has a length of that is 6 more than its width the perimeter of the frame is 52 inches. what is the l
Hitman42 [59]

Answer:

Width = 10 and Length = 16

Step-by-step explanation:

→ Assign variables to the length and width

width = x so length = 6 + x

→ Make an equation

x + 6 + x + x + 6 + x = 52

→ Simplify

4x + 12 = 52

→ Minus 12 from both sides

4x = 40

→ Divide both sides by 10

x = 10

→ Resubstitute into the previously assigned values

width = 10 so length = 16
