I'm basically seeing if I take one of the numbers out then cross multiply, and see if I get the same number I took out or not.
6. I'm taking the 2 out for this one.
6*8=48
48/ 24=2
it should be proportional.

7.I'm taking out the 2
5*8= 40
40/25= 1.6
this one should not be proportional

Evgen [1.6K]

Answer:

2(y+2)

Step-by-step explanation:

Let

y --->Mala's age

x---> sister's age

we know that

x=y+4 ---> equation A

so

The sum of ages of the sisters is

x+y

substitute equation A in the expression of the sum of ages

(y+4)+y=2y+4

simplify

2(y+2)

A teacher writes the following product on the board:
GREYUIT [131]

Answer:

Zhenghao is correct

Step-by-step explanation:

We have that:

(2x+3)(x + 4) = x² + 7x + 12

The only two factors of  x² + 7x + 12 different from 1 ,-1 and and itself are (2x+3) and (x + 4)

If Hafsana says that (x + 3) is a factor of x² + 7 + 12, He or she is not correct.

If Zhenghao says that x² + 7x + 12 is divisible by 2x + 3, He or she is correct because (2x + 3) is a factor of x² + 7x + 12
