Step-by-step explanation:

For the first two problems, there is nothing that I should solve for, lmk and I will solve it again. For now, I just solved for the sector.

Step-by-step explanation:

1. s=(7pi)/2

2. s=14pi/5

3. 240

4. s=((pi)r(<APC))/180

the circumference of the circle is 20pi and ABC is 16pi so the minor arc AC is 4pi=s

4pi=(pi)(10)(x)/180

x=72

Hope that helps :)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)
