Multiply out 5x(2x-3y)

Mathematics

dybincka [34]3 years ago

You start by distributing the 5x, so that it’s 5x(2x) and 5x(3y). That becomes 10x^2 and 15xy. Put it back, and it’s 10x^2 - 15xy.

Expand

5x × 2x + 5x × -3y

Rake out the constants

(5 × 2)x + 5x × -3y

Simplify 5 × 2 to 10

10x + 5x × -3y

Use the product rule: x^ax^b = x^a + b

10x^2 + 5x × -3y

Simplify 5x × -3y to -15xy

<u>= 10x^2 - 15xy</u>

You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number?
nlexa [21]

Answer:

C) 1/4

Step-by-step explanation:

Because you have six-sided dice there are 3 odd numbers and 3 even numbers. That means you have a 1/2 for getting either a odd or even number. So we would add 1/2 + 1/2 because you are rolling two times and both have a 1/2 of getting either a odd or even number. 1/2+1/2 = 1./4 which would be your answer.

Hope this helped! Have a good day/night and good luck! Stay safe!!

Clare is paid $90 for 5 hours of work. At this rate, how many seconds does it take for her to earn 25 cent?
Alla [95]
50 secs

as $90÷5hrs= 18 $ per hrs

$18÷60min=$0.30 per min

$0.30÷60sec=$0.005 per sec

$0.25÷$0.005= 50sec to make $0.25

so 50sec is the answer
