Answer:

53

Step-by-step explanation

8 - 8/2 (this is a fraction) is also known as

8-4 because 8 divided by 2 is 4

so 8-4 = 4

next 4 + 7^2

why is the 2 in the air????

so that's called an exponent, in this case the two means 7 x 7, it is multiplying by itself, thats the essence of exponents. I can do this for exponent 3,4,5,6,7 and so forth. Anyways, 7^2 or 7x7=49

Knowing this its now 4+49= 53

Answer:

E. x² + 11x - 42 = 0

Step-by-step explanation:

let the square sides be x

A = bh = (x + 3 + 3)(x + 2 + 3) = 72

(x + 6)(x + 5) = 72

x² + 11x + 30 = 72

x² + 11x - 42 = 0

Which is true about the completely simplified difference of the polynomials a3b 9a2b2 − 4ab5 and a3b − 3a2b2 ab5?.
PtichkaEL [24]

The simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).

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

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

Let's simplify the two of the given polynomials, therefore, find the difference between the two given polynomials.

a^3b+9a^2b^2 - 4ab^5 - (a^3b - 3a^2b^2+ab^5)\\\\= a^3b+9a^2b^2 - 4ab^5 - a^3b + 3a^2b^2-ab^5\\\\\text{Bring Like terms together}\\\\=a^3b - a^3b+9a^2b^2+3a^2b^2 -4ab^5-ab^5\\\\= 12a^2b^2-5ab^5

Hence, the simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).
