Solve each equation for x.
a. x−10=0
b. x/2+20=0
c. demanding dwight insists that you give him two solutions to the following equation:
(x−10)(x/2+20)=0
can you provide him with two solutions?

a) x = 10

b) x = -40

c) x = 10, -40

Step-by-step explanation:

a)

Taking 10 to the right hand side 10 becomes positive

So x = 10

b)

Taking 20 to the right hand side 20 becomes negative

Multiplying both sides by 2

So, x = -40

c)

Hence, x = 10, -40

So, two solutions can be provided

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
