Just add 3, 1, 4, and 2 which will give you b^10 :)

Are those supposed to be exponents? When multiplying exponents you add them together

b^3 * b^1 * b^4 * b^2
3 + 1 + 4 + 2 = 10

Answer: b^10

Y=1/2x +5<br> Y=-3/2x-7<br> Find x and y

gayaneshka [121]

I'm going to use the substitution method.

If y = - 3/2 - 7, then:

1/2x + 5 = - 3/2x - 7

Combine like terms:

4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)

Simplify to get:

x = - 6.

Plug - 6 back in for x in either equation.

Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.

X = - 6, Y = 2

What is the factored form of 6n4 – 24n3 + 18n?

seropon [69]

Answer: Its factored form will be

$6n(n-1)(n^2-3n-3)$

Step-by-step explanation:

Since we have given that

$6n^4-24n^3+18n$

So, we need to factor ,

$6n(n^3-4n^2+3)$

Now,

$\text{Let }p(n)=n^3-4n^2+3$

Now, by hit and trial method, we put n=1,

$p(1)=1^3-4\times1^2+3=1-4+3=1-1=0$

$n=1\\n-1=0$

So, n-1 is also factor of p(n).

Now,

$\frac{n^3-4n^2+3}{n-1}=n^2-3n-3$

So, its factored form will be

$6n(n-1)(n^2-3n-3)$

Find the lest number which is exactly divisible by 36 & 90 Maths

prisoha [69]

Answer:

180

Step-by-step explanation:

You need to find the HCF of 36 and 90.

<u>Prime factors of each:</u>

36 = 2*2*3*3
90 = 2*3*3*5

<u>HCF includes all prime factors of both numbers:</u>

HCF(36, 90) = 2*2*3*3*5 = 180
