Sholpan [36]
-19x+9 is the answer
First distribute -5 and -7 once you that you’ll get -5x+30 and -14x-21 so now you have -5x+30-14x-21 you then are gonna combine like terms so -5x-14x is -19x and 30-21 is 9 and so you’ve simplified all you can and end up with -19x+9

A school club wants to collect at least 500 canned goods for a school food drive. The club has already collected 30 canned goods
ArbitrLikvidat [17]

Answer:

The correct answer is 10n ≥ 470.

Step-by-step explanation:

Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.

They already collected 30 canned goods, therefore we can subtract this quantity from out goal.

500 - 30 = 470

Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.

Find the perimeter of the triangle defined by the coordinates (9, 0), (-5, 0), and (-10, 6). (Round to nearest tenth)
Masteriza [31]
The perimeter is 41.7

Find the length of each side using the distance formula:
d=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+14^2}=\sqrt{196}=14&#10;\\&#10;\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}=7.8&#10;\\&#10;\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}=&#10;\\19.9

Adding the side lengths, we have
14+7.8+19.9=41.7
