Answer:
13
Step-by-step explanation:
FC + CB = 1/2 CD + 1/2 AB = 1/4 DE + 1/2 AB
= 1/4 * 12 + 1/2 * 20 = 3 + 10 = 13

Good evening ,
Answer:
the smaller integer is 4
the larger integer is 6
4²=16
6+10=16
Step-by-step explanation:
Let x be the smaller integer then the larger one is x+2
the square of the smaller integer is 10 more than the larger integer means
x² = (x+2)+10 ⇔ x² - x - 12 = 0
solve the last equation and you will get
x=4 or x=-3
since -3 is not an even integer then x=4
therefore x+2=6.

Answer:
9
Step-by-step explanation:
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 6^0)^2
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 1)^2
2^28(3^-2/2^3)^4 x 243^2/256^2
2^28 x 1/2^12 x 3^8 x 243^2/256^2
243^2 x 1 x 2^28/256^2 x 3^8 x 2^12
2^28 x 243^2/2^12 x 3^8 x 256^2
2^16 x 243^2/3^8 x 256^2
2^16 x 3^10/2^16 x 3^8
=3^2
=9
Answer:
