Someone please help me with this.

17

Step-by-step explanation:

What we have to realize is that RS + ST = RT. Since we know the value of all, let's substitute inside the equation.

Now let's try and solve for x by isolating the variable on one side.

Combine like terms:

Subtract 18 from both sides:

Divide both sides by 7:

Now that we know the value of x, we can substitute it back into the equation for RS, .

Hope this helped!

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
