Find 3 consecutive even integers if their sum decreased by 10 equals -22
Orlov [11]
Three consecutive even integers can be represented by x, (x+2), and (x+4).

(x + (x + 2) + (x + 4)) - 10 = -22   Get rid of the parentheses
    x + x + 2 + x + 4 - 10 = -22   Combine like terms (x + x + x) and (2 + 4 - 10)
                               3x - 4 = -22   Add 4 to both sides
                                    3x = -18   Divide
                                      x = -6
Check you work.

x = -6
x + 2 = -4
x + 4 = -2

(-6 - 4 - 2) - 10 = 22
-12 - 10 = -22

So, your three integers are -6, -4, and -2 .

Which equation results from taking the square root of both sides of (x + 9)2 = 25?
Alex_Xolod [135]

Answer:

√2.37+ 3 √9 = √5. 3 is the last one

x+9 =+25

Step-by-step explanation:

(x+9)2= 25   This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24

We can also see 18+7 =25

√5.65 √5

this is 25 = 5 so it's the last one.

as 2.37+ 3 √9 = √5. 3
