This is the list of choices that accompany that question:
A) The number is greater than 2.
---> FALSE BECAUSE IT INCLUDES GREATER THAN 10, AND 10 IS THE LAST NUMBER OF THE SET.
B) The number is not divisible by 5.
----> FALSE BECAUSE 10 IS DIVISIBLE BY 5.
C) The number is even or less than 12.
---> THIS CAN BE RIGHT BECAUSE 1) ALL THE NUMBERS SHOWN ARE EITHER EVEN OR LESS THAN 12 AND THE DEFINITION, AND 2) THE DEFINITION DOES NOT INCLUDE A NUMBER OUT OF THE NUMBERS SHOWN.
D) The number is neither prime nor composite.
---> FALSE BECAUSE ANY NUMBER IS EITHER PRIME OR COMPOSITE.
E) The square root of the number is less than 3. ---> FALSE BECAUSE THE SQUARE ROOT OF 10 IS GREATER THAN 2.
Answer:
900.
Step-by-step explanation:
1) the initial area is: A₀=0.5*base*h;
2) the final area is: A=0.5*(5*base)*(5*h).
It means, that 25A₀=A, then A=900 [cm²].
a = 3, b = 4, and c = 2
a + b = c
3 + 4 = 2
3a + 4b = 2c
<u> -4 -4
</u> <u>3a</u> = <u>-6c
</u> 3 3
a = -2
3a + 4b = 2c
<u>-3 -3
</u> <u>4b</u> = <u>-1c</u>
4 4
<h2>
a = 2c/3 - 4b/3</h2>
