Please help I’ll give brainiest.

h(3) = -4

h(-3) = -16

Step-by-step explanation:

The formula is h(x)= 2x-10. So you have to plugin 2x-10 into h(3). Same thing for h(-3).

h(3) = 2*3-10

h(3) = -4

h(-3) = 2*-3-10

h(-3) = -16

I hope this helps you!

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
