Answers

(6x^4+7)(6x^4-7) because when you multiply these two factors the two middle terms are +42x^4 & -42x^4 so they cancel out leavinf the first and last terms

The correct answer is option C) (6x4 – 7)(6x4 + 7).

Simplify: 9(a + b) + 4(3a + 2b)A) 13a 13b
B) 21a + 17b
Eliminate
C) 21a + 2b
D) 38ab

Answers

Answer:

Option (B) is correct.

The simplified form of the given expression $9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)$ is $21a+17b$

Step-by-step explanation:

Given: expression $9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)$

We have to simplify the given expression $9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)$ and choose the correct option from given options.

Consider the given expression $9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)$

Apply distributive rule, $a\left(b+c\right)=ab+ac$

We have,

$=9a+9b+12a+8b$

Adding like terms,

LIKE TERMS are terms having same variable with same degree.

$9a+12a=21a\n\n \:9b+8b=17b$

We have,

$=21a+17b$

Thus, The simplified form of the given expression $9\left(a\:+\:b\right)\:+\:4\left(3a\:+\:2b\right)$ is $21a+17b$

b) 9(a+b)+4 (3a+2b)=21a+17b

(6p + 4q)(-2p + 9q) simplify please help me with this

Answers

$(6p + 4q)(-2p + 9q) =\n \n=-2p\cdot 6p + 9q\cdot 6p -2p\cdot 4q + 9q\cdot 4q=\n \n=-12p^(2)+54pq-8pq+36q^2=\n \n =-12p^(2)+46pq +36q^2$

Well first you have to multiply using FOIL, so...
-12p² + 54qp -8qp +36q²
-12p² + 46qp + 36q² is the simplified answer
Hope that helps :)

i have this for my math review & i just don't seem to get it...what is (.9x+.8y)^2

Can you take the quantity [ x + y ] and square it ?

Can you take the quantity [ x + 2y ] and square it ?

Then you should have no trouble with the square of (.9x + .8y) .

The nth term of a sequence is 3n+5 to the 6th terms sequence

Answers

Answer:

Hey!

The 6th term of your sequence is 23!

Step-by-step explanation:

This is how you get it...

1) T6=3n+5 (the 6th term and the equation...)

2. We now do T6=3(6)+5 (3 x 6 then add 5)

3. In other words... T6=18+5

4. We work it out 18 + 5 = 23
