16 + 24 Select the TWO expressions that are equivalent to the given expression.
Select one or more:

a.
4(3 + 6)

b.
4(4 + 6)

c.
4 (6 + 12)

d.
2(8 + 12)

B) 4(4+6)

Step-by-step explanation:

when you have a number in front of parenthesis you are multiplying that number by what is in the parenthesis. so

4×4 = 16

4×6 = 24

then the equation becomes

16 + 24

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°

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
