Hey luvs I need help with this please help me

area of the big triangle is QS*RT, where we know the QS

so we need to derive the area of big triange

the big triange is sum of the larger triangle (QT*RT) + smaller one (TS*RT)

so RT*(5+2.2)=RT(5)+RT(2.2)

the rest is simple to solve

Step-by-step explanation:

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
