Answer:

x=15

Step-by-step explanation:

You need to do proportions.

Since 16/12 = 1.3333333333333333333,

than you need to divide 20 by 1.323333333, so 20/1.3333333333333= 15

2³+2²+2÷2²+2+1=2 prove that this relation is true for any natural numbers
UkoKoshka [18]

So, this question is basically asking us "If we had an x instead of a 2, would this be true?" We can try and see what we get:

\frac{x^3+x^2+x}{x^2+x+1}=x

So, if we want to show this we have to change the numerator or denominator in such a way that we can cancel some common factors. Notice that x^3+x^2+x=x(x^2+x+1)

If we replace the factored numerator with the original one, we get:

\frac{x(x^2+x+1)}{x^2+x+1}=x \implies \\ x=x

Since we have an equality, this relation is proved.

The cost of a bagel and a cup of coffee is $2.35. The cost of 2 bagels and a cup of coffee is $4.20. What is the cost of one cup
Gnesinka [82]

Hey!

--------------------------------------------

Solution and Answer:

4.20 - 2.35 - $1.85 per bagel.

1.85 x 2 = $3.70 for 2 bagels.

4.20 - 3.70 = $0.50 per coffee.

Polynomial help! 40 pts, please show all work for question 49 part a and b
hoa [83]

Answer:

4x^2 +84x+440

840 in^2

Step-by-step explanation:

The length of the picture and frame is x+ 22+x= 2x+22

The width of the picture and frame is x +20+x = 2x+20

Area is length times width

A = (2x+22) *(2x+20)

We can FOIL to find the area

first 2x*2x = 4x^2

outer 2x*20 =40x

inner 2x*22 = 44x

last = 22*20 = 440

Add these together

4x^2 +40x+44x+440

4x^2 +84x+440

b.  x=4

4x^2 +84x+440

4(4)^2 +84(4) +440

4*16 +336+440

64+776

840
