Please Helpp !! Last week, Clay had a beginning balance of $50 in his account. He wrote 2 checks for $23 each from his checking account , withdrew another $5, and finally made a deposit of $22. Part A: Write an expression and your answer to show his final account balance at the end of the week 23 * 2 = 46
Part B: Explain in words, what Clay should do to get his accaunt balance to zero?

Make a withdrawal of $21

Step-by-step explanation:

Given

(2 checks)

Solving (a): Show final balance

The transaction can be expressed as:

i.e.

Add cash inflow

Subtract outflow

This gives:

Solving (b): Get account balance to 0

To get his account to 0, he needs to make a withdrawal of the exact amount in his account (i.e. $21)

So, all he needs to do is to make a withdrawal of $21

stethere all not eveanp-by-step explanation:

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)
