Answer:
(x+1)(x-5)
Step-by-step explanation:
(x+a)(x+b)=x²-4x-5
then a+b=-4 and a*b=-5
so a=-1 and b=5
Answer:
3x
7-k
m/4
(5x)+12
Step-by-step explanation:
most of the words like and are just fillers. and basically means together in this instance
Answer:
Angle A would be 10
Step-by-step explanation:
The reason is because 10+20 is 30 so if you got from 30 and skip by 20's you'd get 170
Let the length of the box be X cm.
6 * 12 * X = 1252
X = 17.4 inches
therefore the lenght is roughly about 17 inches.

Answer:
and
Step-by-step explanation:
<em>hey there,</em>

< The way you solve right angle triangle problems are using the Pythagorean theorem. (I hope you have already learned it but if you haven't feel free to ask me.)
Pythagorean theorem states:
The two sides of the triangle that touch the right angle are (x+5) and (x-3).
Those two values count as "a" and "b". "c" would be 9.
Let's put them into the equation now.
Simplify:
From there, you can solve to x (it might be a little tricky, so sorry if you don't understand these steps).
final answer: and >
