I did the math and it is 4x
Answer:

Step-by-step explanation:
- this can be done by simple manipulation .
- in the given equation, A is the subject.
- so, by the above statement you can understand the meaning of making something as a subject.
- given equation: A = 1/2 bh
- multiply both the sides by 2,
2A = bh
- divide both the sides by h,

so, the required form is : 
<u>2 - z</u> + <u>5z × 3</u>
4 z
<u>2 - z</u> + <u>15z</u>
4 z
<u>z(4)(z</u>) + <u>15z(z)(4)</u><u />
4(z) 4(z)
<u> 4z²</u> + <u> 60z²</u>
4z 4z
<u>64z²</u>
4z
16z
200-90= the answer then find d which is easy
