PLEASE HELP

18 sq.m

Step-by-step explanation:

Area of the part with cement = area of backyard - area of grass part

Backyard:

length = l = 6m  ; Width = w = 4 m

Area of backyard = l * w = 6*4 = 24 sq. m

Grass part:

l = 3 m ; w = 2 m

Area of the grass part = 3*2 = 6 sq.m

Area of the part with cement = 24 - 6 = 18 sq.m

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

huh? im pretty sure it is in 199
