Answer:

- 2a² - 5a + 4ab - 2b + b²

Step-by-step explanation:

Distributing the parenthesis gives

= - 2a² - 2ab + 10a - 15a + 6b + 6ab + b² - 8b ( collect like terms )

= - 2a² + (10a - 15a) + (- 2ab + 6ab) + (6b - 8b) + b²

= - 2a² - 5a + 4ab - 2b + b²

------------------------------------------------------

coefficient of the a² term is - 2

coefficient of the ab term is + 4

coefficient of the b term is - 2

Given h(x) = 4x – 5, solve for a when h(x) = 7.

Elenna [48]

h(x)=4x-5

$\\ \sf\longmapsto h(7)$

$\\ \sf\longmapsto 4(7)-5$

$\\ \sf\longmapsto 28-5$

$\\ \sf\longmapsto 23$

Suppose you have 18 objects (10 of type A, 5 of type B, and 3 of type C). Objects of type A are indistinguishable from each othe

Paladinen [302]

Answer:

$\binom{18}{5}= 8568$

Step-by-step explanation:

Note that we have in total 18 items. Even though we are given information regarding the amounts of items per type, the general question asks the total number of ways in which you can pick 5 out of the 18 objects, without any restriction on the type of chosen items. Therefore, the information regarding the type is unnecessary to solve the problem.

Recall that given n elements, the different ways of choosing k elements out of n is given by the binomial coefficient $\binom{n}{k})$ .

Therefore, in this case the total number of ways is just $\binom{18}{5}=8568$
