The sum of 3 consecutive even integers is 18

larisa [96]

Answer:

4,6,8

Step-by-step explanation:

Let x = 1st even integer

x+2 =2nd even integer

x+4 =3nd even integer

x+ x+2 + x+4 = 18

Combine like terms

3x+6 = 18

Subtract 6 from each side

3x+6-6=18-6

3x= 12

Divide by 3

3x/3 =12/3

x = 4

x+2 = 6

x+4 = 8

Please help me with this one!!

Tema [17]

Answer:

$21 in^{2}$

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. 9.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

$A=bh\frac{1}{2}$

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply that by 4. 12.

Add 12 and 9 together, and you get:

$21 in^{2}$

I hope this helps!

Which is equivalent?

Arlecino [84]

Steps to simplify:

(2x + 3)(x - 7)

~Use FOIL to multiply

(2x * x) + (2 * -7) + (3 * x) + (3 * -7)

~Simplify

=2x² - 14x + 3x - 21

~Combine Like Terms

2x² + (-14x + 3x) - 21

~Simplify

2x² - 11x - 21 (Option 2)

Best of Luck!

Ryan is performing an experiment. He starts with a solution that has a temperature of 12.2°C. He lowers the temperature 5 times

Anon25 [30]

Answer: The equation that can be used to find x, is given by

$-14.61^\circ C=12.2^\circ C-5x$

Step-by-step explanation:

Let the number of degrees he lowered the temperature by each time be 'x'.

Temperature he starts with = 12.2° C

Temperature he stopped with = -14.61° C

According to question, it is said that he lowers the temperature 5 times by the same amount each time.

So, it becomes,

$-14.61=12.2-5x\\\\-14.61-12.2=-5x\\\\-26.81=-5x\\\\\frac{26.81}{5}=x\\\\5.362^\circ C=x$

Hence, the equation that can be used to find x, is given by

$-14.61^\circ C=12.2^\circ C-5x$
