1) What is the GCF for the polynomial 4x3 - 2x2y?
Dafna1 [17]

(1)the GCF for the polynomial 4x^3 - 2x^2y

4x^3 = 2*2* x* x* x

2x^2y = 2*x*x*y

Greatest common factor  is 2*x*x = 2x^2

(2) the GCF for the polynomial 8x^4y + 6x^2y^2

8x^4y = 2*2*2*x*x*x*x*y

6x^2y^2 = 3*2*x*x*y*y

GCF is  2*x*x*y=2x^2y

(3) the GCF for the polynomial12x^3y^2 - 20x^5y^3

12x^3y^2 = 2*2*3*x*x*x*y*y

20x^5y^3=5*2*2*x*x*x*x*x*y*y*y

GCF is 2*2*x*x*x*y*y= 4x^3y^2

(4) the GCF for the polynomial -10x^3y^4 - 16x^5y^2

-10x^3y^4 =-2*5*x*x*x*y*y*y*y

-16x^5y^2=-2*2*2*2*x*x*x*x*x*y*y

GCF is -2*x*x*x*y*y= -2x^3y^2

Solve for c.<br> 8<br> ge-2<br> =<br> co!<br> 2<br> C-12
hjlf

Answer:

-5

Step-by-step explanation:

8/3c-2=2/3c-12

first we'll do the LCM of both sides denominator 3 and 3=3

and multiply this with both side

3×8/3c - 2×3= 3×2/3c - 3×12

8c-6= 2c-36

8c-2c=-36+6

6c=-30

c=-30/6

c= -5

How much interest will $875.00 earn after 3 months at 5.5%?
ZanzabumX [31]

Answer:

I = Prt

Substitute the given information. Remember to write the percent in decimal form. I = (500)(0.06)(3)

Simplify. I = 90

Check your answer. Is $90 a reasonable interest earned on $500 in 3 years? In 3 years the money earned 18%. If we rounded to 20%, the interest would have been 500(0.20) or $100. Yes, $90 is reasonable.

The simple interest is $90.

Step-by-step explanation:

Hope this <u><em>Helped!</em></u> :D
