We can think of factoring as the opposite of the distributive property. If we take ax+bx, we just factor to get x(a+b) - it's the same thing. If you think of it like that, it provides great insight and a thoughtful memory strategy. Hope this helps!
Answer:
-2
Step-by-step explanation:
2x+5-7x=15
Combine like terms
-5x+5=15
Subtract 5 from both sides
-5x=10
Divide -5 from both sides
x=-2
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish

In 4.75 the 7 makes it round up to 5
The side |rs| is congruent to side |ac| which is 14 ft.
<h3>What are congruent triangles?</h3>
Congruent triangles are two similar triangles that have corresponding sides and angles and they are of equal measure.
The figures from the textbook illustrate that following rotation, the two triangles are congruent.
This signifies that the angles and sides of the first triangle are equal to the angles and sides of the other triangle.
Therefore:
- ab = tr = 10 ft
- ac = rs = 14 ft
- bd = ts = 20 ft
