Multiply and simplify. (3x+5)(2x2−3x+2) Enter your answer, in standard form, in the box.

Sveta_85 [38]

Answer:

$6x^3+x^2-9x+10$

Step-by-step explanation:

We have the product, $(3x+5)(2x^{2}-3x+2)$ .

On simplifying the product, we get,

$(3x+5)(2x^{2}-3x+2)$

i.e. $6x^3-9x^2+6x+10x^2-15x+10$

i.e. $6x^3+x^2-9x+10$

Thus, the standard form of the product $(3x+5)(2x^{2}-3x+2)$ is $6x^3+x^2-9x+10$ .

A local charity sponsors a 5K race to raise money. It receives $25 per race entry and $5,000 in donations, but it must spend $5

kenny6666 [7]

they receive 25 per entry but 5 goes towards the cost of the race

so 25-5 = 20 per entry is for the charity

so 20x + 5000 = 25000

subtract 5000 from each side

20x= 20000

divide both sides by 20

x = 20000/ 20

x = 1000

they need at least 1000 entries to make 25000

so to make more than 25000, they need 1001 entries
