In math, a factor is a number being multiplied; for instance, if 7x5=35, 7 and 5 are both factors.

Answer:

y^2+xy+x+3y+2

Step-by-step explanation:

first of all we have to multiplies the y in the second bracket for all numbers in the first bracket.

so we have:

xy+y^2+2y

now we have to do the same with 1

x+y+2

now we have to unite the two solutions

xy+y^2+2y+x+y+2

at least we have to added up the similar terms (that have the same literal part)

y^2+xy+x+3y+2

Answer/Step-by-step explanation:

Recall: $x^{-a} = \frac{1}{x^a}$

a. $4^{-3} = \frac{1}{4^3} = \frac{1}{64}$

b. $13^{-2} = \frac{1}{13^2} = \frac{1}{169}$

c. $(-3)^{-2} = \frac{1}{-3^2} = \frac{1}{9}$

Pedro has 3 boxes of 6 markers. Rafael has 5 boxes of 5 markers. One of the friends arranges all his markers into 2 equal groups

Komok [63]

Answer:

see below

Step-by-step explanation:

Pedro has 3 boxes of 6 markers.

3*6 = 18 markers

We can divide this by 2 because this is even

18/2 = 9

There are 9 in each group

Rafael has 5 boxes of 5 markers

5*5 = 25

We cannot divide this by 2 because this is odd

A rancher has 4 comma 700 feet of fencing available to enclose a rectangular area bordering a river. he wants to separate his co

guapka [62]

Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2

This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
