How do you solve 4(3x-5) using "distributive property" and "combining like terms"

1 answer:

3 0

Just multiply the parentheses by 4. So you end up with 12x-20. If your teacher wants you to simplify then go ahead and divide to get a simplified equation but if not, then you're set.

27. (-2 + √-8) + (5 - √-50) standard form ?

marin [14]

We can break this down by removing the parenthesis first:

-2 + $\sqrt{-8}$ + 5 - $\sqrt{-50}$

In order to continue, you have to simplify the square roots by factoring it and taking out i:

-2 + $2i\sqrt{2}$ + 5 - $5i\sqrt{2}$

Combine like terms:

-3 - $3i\sqrt{2}$ <-- that's the answer

Hope I helped :)

an angles measure is 6 degrees more than 3 times the measure of its complwment. find the measure of the angles.

irina1246 [14]

Answer:

The angles are 22.5 and 67.5.

Step-by-step explanation:

A complement is the angle that when added to the given angle gives 90 degrees.

Therefore, the angle x is 3 times larger than its complement.

This means that x is 3/4 of 90 degrees and complement is 1/4 of 90 degrees.

Therefore, the angles are 22.5 and 67.5.

On average, Haley is able to read 4 5/6 Chapters in the her book each week . How many weeks will it take Haley to read 9 2/3 Cha

Step2247 [10]

Answer:

2 weeks

Step-by-step explanation:

y = mx + b

y = total number of chapters read = $9\frac{2}{3}$

m = number of chapters read per week = $4\frac{5}{6}$

x = number of weeks = what we're solving for

b is not needed to find this solution

$9\frac{2}{3}$ = $4\frac{5}{6}$ x divide $4\frac{5}{6}$ from both sides

x = 2 weeks
