A square has an area that is less than 100m^2. What is a reasonable range for the graph of the square side?A. 0< y < 100

B. 0< y < 50

C. 0 < y < 25

D. 0 < y< 10

Answers

Answer 1
Answer: The area of the square is obtained by taking the square of the length of one side. Since it is said that the area of the square is less than 100 m^2, taking the square root of that where: sqrt (100) = 10, the side of that square should be less than 10 as well. Among the choices, D. 0 <y <10 (where y = length of side of square) is the correct answer.

Apples are on sale for $1.20 a pound. Logan bought 3/4 of a pound. How much money did he spend on apples

Answers

What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
So she spent 90 cents on apples
Hope I helped :)
(3)/(4) * 1.20 = (3.6)/(4) = \huge{\boxed{0.9}}

ok well the answer will be 2 because 8+8=16 and 8 can go into 16 2 times.
the answer is 
2/1 
because 8 times 2 is 16 and if  you divide 16 by 8 u will get 2 and 8 divided by 8 is 1

The answer is 3x^4-13x^3-x^2-11x+6.

Solution:

Use algebraic identity: a^m* a^n=a^(m+n)

For example: x^2* x=x^(2+1)=x^3

Given expression (x^2-5x+2) and (3x^2+2x+3).

To multiply these equations.

(x^2-5x+2)*(3x^2+2x+3)

             =x^2(3x^2+2x+3)-5x(3x^2+2x+3)+2(3x^2+2x+3)

             =(3x^4+2x^3+3x^2)+(-15x^3-10x^2-15x)+(6x^2+4x+6)

             =3x^4+2x^3+3x^2-15x^3-10x^2-15x+6x^2+4x+6

Combine like terms together.

             =3x^4+(2x^3-15x^3)+(3x^2-10x^2+6x^2)-15x+4x+6

             =3x^4-13x^3-x^2-11x+6

(x^2-5x+2)*(3x^2+2x+3)=3x^4-13x^3-x^2-11x+6

Hence the answer is 3x^4-13x^3-x^2-11x+6.
