Answer:

22, 24

Step-by-step explanation:

consecutive even integers are two numbers apart

x = 1st even integer

x+2 = next consecutive even integer

x+(x+2)=46

2x+2=46

2x=44

x=22

The two consecutive even integers are 22 and 24

The area of triangle ABC is?

melisa1 [442]

Answer:

$A(\triangle ABC) =17.5 \: {units}^{2}$

Step-by-step explanation:

AB = 4 - (-3) = 4 + 3 = 7 units

BC = 3 - (-2) = 3 + 2 = 5 units

$A(\triangle ABC) = \frac{1}{2} \times AB\times BC \\ \\ A(\triangle ABC) = \frac{1}{2} \times 7\times 5 \\ \\ A(\triangle ABC) = \frac{1}{2} \times 35 \\ \\ A(\triangle ABC) =17.5 \: {units}^{2}$

Factor completely 8y^3+16y^2

gregori [183]

Answer:

8y^2(y + 2)

Step-by-step explanation:

The given expression is 8y^3 + 16y^2

Let's find the greatest common factor of 8y^3 and 16y^2

The GCF is 8y^2. Let's take out the GCF outside and write the remaining terms as follows

8y^2 (y + 2)

Therefore, the factors are 8y^2 and (y + 2)

That is 8y^3 + 16y^2 = 8y^2(y + 2)

Thank you.
