Simplify
6(2x + 1) = 2(5x + 2)
18

156x²

Step-by-step explanation:

6×2x=12x+1=13x

2×5x=10x+2=12x

you multiply those numbers together because if the is no sign like addition or subtraction its considered multiplication so you multiply 13x by 12x

and you will get: 156x²

cuz also is x is multiplied by x it turns into a power/index

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
