12 + 3 [5 + (4-2)] =
12 + 3 [ 5 + 2 ] =
12 + 3 [ 7] =
12 + 21 =
33 <===
Step-by-step explanation:
mA=cosA=17/38
A=cos inverse of 17/38
A=63 degrees
So you have two parts to eliminate, (x+1) is being multiplied by its reciprocal so you can eliminate that along with the (2x-4).
this brings you to to have 1=(-4/(2x-4)) meaning that if tou multiply both sides by 2x-4 you end up with 2x-4=-4 and can add 4 to both sides, getting 2x=0 or x=0 for your answer. :DDDD
Both the work and explanation is in the picture.
The rest of the question is missing.
Equation needed:
240 = 4x + 32
Take it from here.
