Factor out the greatest common factor: -16x? + 12x?

Mathematics
1 answer:
svlad2 [7]4 years ago
7 0

Answer:

4x is the greatest common factor of those two.

Step-by-step explanation:

(-16x + 12x)

4x (-4 + 3)

4x is the GCF

Why you may ask is 4x the GCF because when you divide 4x from both you're left with -4 + 3...... you can't take out the negative from the 16 because when you check your work negative 4x times 3 gives you negative 12x which isn't the equation you started with. So positive 4x times 3 give you 12x.

Hopes this helps!!!

Answer:

18i, -7-i, -6+18i

Step-by-step explanation:

1. √-324

first take out the negative as √-1=i

√-324= i√324

324 =2*162

324=2*2*81

324=2*2*9*9

i√324=i√2*2*9*9= i* 2*9= 18i

3.

-4+7i-3-8i combine like terms

-4-3 -8i+7i = -7-i

5.

(1+5i)(4-2i) distribute

1*4 -1*2i +5i*4 -5i*(-2i) multiply

4 -2i +20i +10i² but i²= -1 so

4 -2i +20i -10 combine like terms

-6 +18i

Two polygons whose corresponding angles are congruent and the lengths of the corresponding sides are proportional.

2) When Angelina was born, her grandparents deposited $3000 into a college savings account
notsponge [240]

Answer:

$4,200.00

Step-by-step explanation:

Given that the annual interest pay of $3,000.00 savings is 4%, at the end of the year interest will amount to $120.00. Assume that for 10 years, there is no additional or withdrawal to the savings of $3,000.00, the amount in your savings account at the end of the 10 years would be $4,200.00.

That of course is assuming no money is removed.
