Answer:
<em>-23x-16</em>
Step-by-step explanation:
-4(2x-6)-5(3x+8)
=-8x+24-15x-40
=-23x-16
Number 8 is C 251.2 formula multiply 40*3.14=125.6 125.6*2=251.2
and 9 is C get the area of the rectangle 15*5=75 and now of the circle 3.14*2.5^2=78.5 now divide 78.5/2=39.25 then add 39.25+75=114.3.
Let x = attitude length
x/5 = 14/x
x^2 = 5(14)
x^2 = 70
x = √70
answer is A. √70
