Answer:

Solution set of the quadratic inequality is { x : x ∈ R and x < -2 }

Step-by-step explanation:

Given Quadratic inequality ,

4(x+2)^2

We have to find solution set of the given quadratic inequality.

consider,

4(x+2)^2

transpose 4 to RHS

(x+2)^2

(x+2)^2

Square root both side,

\sqrt{(x+2)^2}

x+2

transpose 2 to RHS

x

x < -2

Solution set of the quadratic inequality = { x : x ∈ R and x < -2 }

Therefore, Solution set of the quadratic inequality is { x : x ∈ R and x < -2 }

The measure of angle R is 148° and the measure of angle S is 85°, find the measure of angle T.
Talja [164]

so you have a 148+85+85=318, 360-318=42 is the measure of angle T because all four angles together make 360
