Answer:
a) 16.7
b) 13.5
Step-by-step explanation:
AC and DE are parallel, so ∠CAB and ∠EDB are corresponding angles, and ∠ACB and ∠DEB are corresponding angles.
Therefore, ΔABC and ΔDBE are similar triangles. We can use this to write a proportion.
a)
(25 + x) / (18 + 12) = x / 12
12 (25 + x) = x (18 + 12)
300 + 12x = 30x
300 = 18x
x = 16.7
b)
x / (7 + 2) = 3 / 2
x = 13.5
I’m not sure what the answer is but you can use an app called Socratic Will help you out
In paraller connection you can calculate the equivlant resistqnce from the relation :
1/R(equi) = 1/R1 + 1/R2 + 1/R3
1/R(equi) = 1/20 +1/20 + 1/10
1/R(equi) = 0.05+0.05+0.1 = 0.2
so, R(equi) = 5 ohms

Answer:
<em>-14x+6</em>
Step-by-step explanation:
first, we distribute the -3.
-3(4x - 2) - 2x=-12x+6-2x
than, we conbide like terms
-12x+6-2x=-14x+6
