Answer:
31x^2-13x
Step-by-step explanation:
to find the perimeter of a triangle, add all sides.
P=a+b+c
P=(5x^2+x)+(8x^2-3x)+(18x^2-11x)
combine like terms
5x^2+8x^2-18x^2= 31x^2
x-3x-11x= -13x
31x^2-13x
Answer:
need the equation written correctly
124=l×w
Answer:
1296000
Step-by-step explanation:
£3.99 divided by 8 is £0.49875
Which, changed into pence and rounded up, is 50p.
£2.79 divided by 6 is £0.465
Which, changed into pence and rounded up is 47p.
50p is bigger than 47p
50 subtract 47 is 3p
The second one has the better value for money as it costs 3p less per battery.
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.
---
Solve for "x":
If amount of compound A is 4x = 477
x = 477/4
Then amt of compound B is 5x = 5(477/4) = 596.25 ml
