Identify which group each number belongs to for each problem. you will check more than one answer for each number. check all groups that apply to each number. -3

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
