Answer:

a)13x+3

b) -3x-13

c)4x^2-24

d)-3x^2 +3x

Step-by-step explanation:

a) combine like terms

5x-3+8x+6 so combine the -3 and +6 and 5x and 8x

So 13x+3

b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.

2x -5 - 5x -8

So -3x-13

c) Distribute the four to everything in the brackets.

4(x^2-6) becomes 4x^2-24

d) Distribute:

-3x (x-1) becomes -3x^2 +3x

18. Make the values have the same denominators.

4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24

Add the values

112/24+129/24= 241/24

Simplify the answer

241/24= 10 1/24

The answer for question 10 1/24 ounces.

Jackson mows 1/3 of his neighbors lawn in 1/6 of an hour. At this rate, how many lawns of the same size could he mow in one hour
IrinaK [193]
He could mow 2 lawns. if he mows 1/3 of the law in 1/6 of an hour, then he can mow 2/3 of the law in 2/6 of an hour. keep adding 1/3 to the amount of lawn mowed as you add 1/6 to the amount of hours, until you hit 6/6 hours, which would be one hour
