Answer:
Step-by-step explanation:
Direct variation has the form y=kx, given k=7 and x=20
y=7(20)=140
$6400 is the amount you will have in 15 years
1. Simplify= xy^3
2. Factorise= (2x+1)(2x-1)

5. Estimate= 415.96
6. Highest Common Factor
70= -70,-35,-14,-10,-7,-5,-2,-1,1,2,5,7,10,14,35,70
98= -98,-49,-14,-7,-2,-1,1,2,7,14,49,98
7. Expand: 4-4x+x^2 Simplify: x^2-4x+4

9. This is actually the easiest you take both the mass and volume and divide them :) which would be 500g<span>÷25cm^3=20g/cm3 </span>
10.
The ones I didn't answer I am not sure about and don't wanna give you any wrong answers :) Hope I helped though!
Answer:
-11(-12)=132
Step-by-step explanation:
First divide 132 by negative 11 and get -12.
Then you connect -12 into the equation by using paraenthisies so its not a mess.
Last check your answer. -11 times -12 is equal to positive 132.
