Make them all have the same denominator
32
25+12 16/32+488/32+124/32+38/32+25/32
Add all of the numerators... to get 691/32+1184/32
1875/32
Simplify to get 58 19/32
B. Five cubed because there at 5 2s there and 2*2*2*2*2 would be the same thing as saying 5^2
FOIL
x^2+11x-9x-99
x^2+2x-99
Answer:
14.1 =x
Step-by-step explanation:
Since this is right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 42 = x /21
21 sin 42 = x
14.05174273 =x
Rounding to the nearest tenth
14.1 =x
