Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:

-n=130 ---> Add n to each side

=130+n ---> Take the square root of each side
m=±

Let's look at the first square number above 130, which is

. <em>m</em> is 12, therefore the next consecutive even integer is 14.

=144
144-14=130
The two consecutive integers are 12 and 14

Answer:
x=29
Step-by-step explanation:
(x+3)+(x-1)+(x+1)=90
x+3+x-1+x+1=90
3x+3=90
3x=90-3
x=87/3
x=29
x+3=32
x+1=30
x-1=28
Checking
(x+3)+(x-1)+(x+1)=90
(29+3)+(29-1)+(29+1)=90
32+28+30=90
90=90
