Answer:
a x (23a+5a^4 - 11)
Step-by-step explanation:
(a x (13a - 6a^4 - 2) + 10a^2 + 11a^5 - 9a
rewite the expression and remove any unnecessary parentheses.
a x (13a - 6a^4 -2) + 10a^2 +11a^5 - 9a
factor the expression.
a x (23a - 6a^4-2+11a^4-9)

Answer:
Rational
Step-by-step explanation:
You can write it as a ratio of a/b
Answer:
The ratio of difference between B and A and the difference between C and B is 3 : 10
Step-by-step explanation:
Three numbers A, B and C are in the ratio of 12: 15 : 25
Let the rational between the numbers be x. Hence the three numbers are :
A is 12x, B is 15x and C is 25x.
Sum of these numbers is 312,
12x + 15x + 25x = 312
52x = 312
x = 6
The rational is 6. Thus the three numbers are:
A = 12x = 12 × 6= 72
B = 15x = 15 × 6 = 90
C = 25x = 25 × 6 = 150
Ratio between the difference of B and A and the difference of C and B to be calculated
Difference between B - A = 90 - 72 = 18
Difference between C - B = 150 - 90 = 60
Thus the ratio of difference between B and A and the difference between C and B is 18 : 60 or 3 : 10

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
