42-x=58

or, -x=58-42

with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.

or, -x= 16

or,x=-16.

therefore x=-16...

Hope this helps you.

Let f(x) = 9 – x^2, g(x) = 3 – x. Find (f – g)(x) and its domain.

nadya68 [22]

Simply the answer is -x^2-x+6 but not sure if you want to factor it but it would be (x-2)(x+3) and not sure how to do the domain

Hlol can u plz solve b no plz plz.....I will mark as brainliest

zimovet [89]

Answer:

Step-by-step explanation:

$Tan \ B =\frac{4}{3} = \frac{opposite \ side \ of B}{adjacent \ side \ of B}$

BC = 15 cm

3x = 15

x = 15/3 = 5

AB =4x = 4*5 = 20 cm

Pythagorean theorem,

AC² = AB² + BC²

= 20² + 15 ²

= 400 + 225

= 625

AC = √625 = 25 cm

AC = 25 cm

$Sin \ A = \frac{opposite \ side \ of \ angle A }{hypotenuse}\\\\ = \frac{BC}{AB}=\frac{15}{25}=\frac{3}{5}$
