Answer 1

Answer:

3.a. TRUE

4. 4 will be in the ones place of its cube.

5. 30,25,20,15,10.

6. trinomials refers to the polynomials with three terms.

Example : 8x + 35+x'2

7.

$(a + b) {}^{2} = a {}^{2} + 2ab + b {}^{2}$

Answer 2

Step-by-step explanation:

I) Empty Set :-

In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero.

2)power law of exponents:-

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. ... Adding the exponents is just a short cut! Power Rule. The "power rule" tells us that to raise a power to a power, just multiply the exponents.

3)true or false

a) true

4) 8×8×8=512

8×8×8=512 so the ones place of the cube will be 2

5)Identify the pattern and find the next two terms:-

30,25,20,15,10

pattern is decreasing by 5

6)trinomial:-

The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations.

7)

${( a+b )}^{2} = {a}^{2} + 2ab + {b}^{2}$

sry I can't do it in paper I think u may understand.....

hope it helps u
