1). 
2). 
Step-by-step explanation:
For multiplication of the rational expressions,

= 
= 
For division of the rational expressions,

= 
=
[When the divisor is a rational expression or a rational number, we change the sign from division to multiplication and reciprocate or flip the fraction.
This is applicable for division of the rational expressions only].
Answer:
-3(10) - 4
Step-by-step explanation:
-3(10 - 4) = -18
-3(10) - 4 = -34
-30 - (-12) = -18
-3(10) - (-3)(4) = -18
-18 = -18

Answer:
x = 87
Step-by-step explanation:
the ratio SR / RV is equal the ratio ST / TU (both ratios are equal to 1), and the angle in the vertex S is the same for both triangles SUV and STR, so we can affirm that these triangles are similar (case S-A-S).
Then, we have that the ratio SR / SV is the same as RT / UV:
SR / SV = RT / UV = 1 / 2
RT * 2 = UV
2*(x - 37) = x + 13
2x - 74 = x + 13
x = 87
