Answer:

3y^{2}+2y-11

Step-by-step explanation:

we have

(-y^{2}-4y-8)-(-4y^{2}-6y+3)

Eliminate the parenthesis

-y^{2}-4y-8+4y^{2}+6y-3

Group terms that contain the same variable

-y^{2}+4y^{2}-4y+6y-8-3

Combine like terms

3y^{2}+2y-11

Please help me asap​
jek_recluse [69]

Answer:

1.1, 12, 99

Step-by-step explanation:

For the first one, we divide 2.5 by 2.2 (2.5/2.2) to get approximately 1.1 kilograms. So it would be the first option. For the second one, we know that 8x6=48, so we multiply 2 by 6 to get 12/48, so it would be the second option. For the third one, we can do this problem: 110/20 to get 5.5. We can multiply 18 by 5.5 to get 99. So that means the answer would be the first option.

Could someone help me please need answer ASAP
Ahat [919]

Here we use altitude rule which states that

Ratio of part of hypotenuse and height= ratio of height and remaining part of hypotenuse .

So here parts of hypotenuses are r and s and h is the hypotenuse. SO we will get

\frac{r}{h} = \frac{h}{s}

Correct option is s.
