Answer:

There is a pattern with the ratios of corresponding sides. You can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. Use patterns like this to problem solve the length of missing sides of similar triangles.

The sum of three consecutive even integers is 36 . find the smallest of them

bonufazy [111]

Answer:

Step-by-step explanation:

You can get the three consecutive integers by using algebraic expressions.

Let's solve.

Let x be the smallest even integer.

Let x+2 be the second even integer.

Let x+4 be the largest even integer.

x+x+2+x+4 = 36

3x+6 = 36

3x = 36-6

3x = 30

x = $\frac{30}{3}$

x = 10

Therefore, 10 is the smallest even integer.

x+2 = 10+2 = 12

The second even integer is 12.

x+4 = 10+4 = 14

The largest even integer is 14.

Let's check by adding the three even integers.

10+12+14 = 36

36 = 36

It's correct.

$= > (x - 2)(x + 5) = 0 \\ \\ = > x(x + 5) - 2(x + 5) = 0 \\ \\ = > {x}^{2} + 5x - 2x - 10 = 0 \\ \\ = > {x}^{2} + 3x - 10 = 0 \\ \\ If \: we \: have \: to \: find \: value \: of \: x \: \\ then \: substitute \: both \: the \: term \: \\ equal \: to \: zero \\ \\ = > x - 2 = 0 \: \: \: \: \: \: x + 5 = 0 \\ \\ = > x = 2 \: \: \: \: \: \: x = - 5 \\ \\ = > x = 2 \: or \: - 5$
