The expression on the left side of an equation is shown below.

-4(x-2)+5x=

if the equation has no solution, which expression can be written in the box on the other side of the equation?

4) x

Step-by-step explanation:

The expression on the left side simplifies to:

-4(x - 2) + 5x =

= -4x + 8 + 5x

= x + 8

To have an equation with no solution, you need the same x term on the right side but a different constant term. The x term on the left side is x. You need x on the right side but with a constant term different than 8.

4) x

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
