When you factor you have to break it into 2 pieces that look like (x+something)(x+something). (The + could also be -).

Find 2 numbers that multiply together to get the last number that can also add or subtract to get the second number. In this case, 1 and 30 work because you can multiply 1 and 30 to get 30, and 30-1 is 29.

The final product is:
(x+29)(x-1) because the last number has to be negative and the middle number has to be positive.

. (02.05 MC) Side AB = 5, side BC = 6, side DE = 5, and side EF = 6. What additional information would you need to prove that ΔA

vaieri [72.5K]

Answer:

Side AC is congruent to side DF

Step-by-step explanation:

We are given that

Side AB=5 cm

BC=6 cm

Side DE=5 cm

Side EF= 6cm

We have to find an additional information would need to prove that $\triangle ABC\cong \triangle DEF$ by SSS.

When two triangles are congruent by SSS it means three sides of one triangle are congruent to corresponding sides of other triangle.

We have in triangle ABC and triangle DEF

$AB\cong DE=5 cm$

$BC\cong EF=6 cm$

$AC\cong DF$

Then , $\triangle ABC\cong \triangle$ DEF

Reason: SSS postulates

Answer: Side AC is congruent to side DF

In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is alcohol and Solution

torisob [31]

Answer:

300ml

Step-by-step explanation:

As values are missing in your question, the complete question is:

In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is 6% alcohol and Solution B is 20% alcohol. She uses 400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 12% alcohol solution?

Considering x=ml of 20% solution B

Therefore, 400+x=ml of resulting 12% solution

Solution A alcohol+ solution B alcohol= Alcohol solution

6% (400)+ 20%x = 12%(400+x) ->(converting percentage into decimal)

.06*400+.2x=.12(400+x)

24+.2x=48+.12x

.08x=24

x=24/.08=300 ml

she used 300 milliliters of 20%Solution B in resulting mixture.
