The answer is 42cm. the area of the rectangle in the middle is 30cm. the area of the triangle on the left is 6cm because the formula is 1/2Bh. B=2 and h=6, so 12/2=6. there are 2 of the triangles however, so you add 30+12=42

What is StartFraction one-half EndFraction x is less than or equal to 18.x ≤ 18
Eduardwww [97]

Answer:

x\leq 36

The solution for x is all real numbers less that or equal to 36.

Step-by-step explanation:

Given expression:

\frac{1}{2}x\leq18

To find the solution for x

Solution:

In order to solve for x , we will make sure to isolate the unknown variable x on left side alone by doing math operations on both sides of the inequality.

We have:

\frac{1}{2}x\leq18

Multiplying both sides by 2.

2.\frac{1}{2}x\leq18\times 2

The 2 on left side will cancel each other leaving x alone.

Thus, we have:

x\leq 36

Thus, solution for x is all real numbers less that or equal to 36.

PLS HELP ME WITH THIS QUESTION IVE BEEN DYING TRYING TO FIGURE THIS OUT
LekaFEV [45]

Answer:

y = -x - 1

Step-by-step explanation:

hello,

this is a line, right?

So the equation should be something like

y = ax+b and we need to find a and b

we can see that the points (-1,0) and (0,-1) are in the line so we can write

0 = a*(-1) + b <=> b - a = 0 <=> a = b

-1 = a*0 + b <=> b = -1

so the equation is

y = -x - 1

hope this helps
