1) Convert feet to inches : so from 7 feet to 84 in
2) Then do straight multiplication : 4 x 84 = 336 in2
Therefore, the answer is 336 inches squared.

Sveta_85 [38]
We set up a proportion: 80/?= 32/100

Cross multiply: 32*?= 80*100
⇒ ?= 80*100/32= 250

80 is 32% of 250.

Cory writes the polynomial x7 3x5 3x 1. Melissa writes the polynomial x7 5x 10. Is there a difference between the degree of the
bagirrra123 [75]

Degree of a polynomial gives the highest power of its terms. Yes there is a difference between the degrees of sum and difference of the polynomials.

<h3>What is degree of a polynomial?</h3>

Degree of a polynomial is the highest power that its terms pertain(for multi-variables, the power of term is addition of power of variables in that term).

Thus, in x^3 + 3x^2 + 5, the degree of the polynomial is 3 as the highest power in its terms is 3.

(power and exponent are same thing)

<h3>What are like terms?</h3>

Those terms which have same variables raised with same powers.

For example, x^3 and 3x^3  are like terms since variable is same, and it is raised to same power 3.

For example 4x^2 and x^3 are not like terms as the variables are same but powers aren't same.

The given polynomials are:

c(x) = x^7 + 3x^5 + 3x + 1\\\\p(x) = x^7 + 5x + 10

Their sum is

c(x) + p(x)  = x^7 + 3x^5 + 3x + 1 + x^7 + 5x + 10 = (1+1)x^7 + 3x^5 + (3+5)x + 11\\\\c(x) + p(x) = 2x^7 + 3x^5 + 8x + 11

(only like terms' coefficients can be added (or subtracted) for addition or subtraction of them )

The sum's degree is 7

Their difference is:

c(x) - p(x) = x^7 + 3x^5 + 3x + 1 - x^7 -5x - 10 = (1-1)x^7 + 3x^5  +(3-5)x -9\\\\c(x) - p(x) = 3x^5 - 2x - 9

Difference's degree is 5

Thus, both's degrees are not same.

Thus, Yes there is a difference between the degrees of sum and difference of the polynomials.

HELP PLEASE WILL GIVE BRAINLIST
rodikova [14]

Answer:

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2   - This can be the expression

B)  = 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

=*40

That was the simplified expression

Answer = 3.14 * 40 = 125.6m^2

2<br> — x = 6<br> 3<br><br> Any help? Please?
Mama L [17]
X = 9
you multiply both sides by 3 because you have to get rid of it and what you do to one side you do to the other then you divide both sides by 2 to isolate the variable. i hope that makes sense.
