Answer:A
Step-by-step explanation:
-7x^2-4x+20
-(7x^2+4x-20)
-(7x^2+14x-10x-20)
-(7x(x+2)-10(x+2))
-(7x-10)(x+2)
Answer:
The answer would be 2/3
Step-by-step explanation:
There are 36 total problems and 24 division problems.
So take 24 over 36 and simplify and you get 2/3.
100 ml of fruit squash
sum the parts of the ratio, that is 2 + 7 = 9 parts
divide 450 ml by 9 to find 1 part
1 part =
= 50 ml
squash is 2 parts = 2 × 50 = 100 ml
lemonade is 7 parts = 7 × 50 = 350 ml
total = 100 + 350 = 450 ml
Answer:
X=2
Step-by-step explanation:
20x+40=80
20x+40-(80)=0
20x-40=0 20x=40
x=40/20
X=2
