Answer:
11 pi over 3
Step-by-step explanation:
you have to convert 3 pi into a fraction and add that to 2 pi over 3. Since the denominators are equal, you have to combine the fractions which would equal 11 pi over 3, if that makes any since
Answer:
h=9cm
P=(x+5)cm
b=(x-3)cm
by the Pythagoras theorem,
h^2=p^2+b^2
9^2=(x+5)^2+(x-3)^2
81=x^2+10x+25+x^2-6x+9
81=2x^2+4x+34
Answer:
-5/8
Step-by-step explanation:
So basically with fractions that have different denominators you have to find the GCF (greatest common factor) of both of them, in this case 8 would be a GCF because it you times 4 and 2 you get a whole number of 8. since we found out the GCF we want to set them equal. so take the 1/4 and multiply both the top and bottom by 2, so we end with 2/8. You set the equation back up (-7/8) + (2/8). and combine the numerators -7+2/8 which ends you with with the answer of (-5/8) :)
