A sheet of paper measures 12 cm by 15 cm. Vince cuts the paper from one corner to the opposite corner,

Len [333]

Answer:45cm

Explanation: If the whole paper is 12 by 15 you have to divide them both by 2!
12 divide by 2=6
15 divide by 2=7.5
Then you have to multiply them together to find the area.
6x7.5=45
So therefore the answer is 45cm.

Use the number 8,6, and 2 and one operation to write an expression that includes an exponent and has a value of 8. Use each numb

podryga [215]

$6 + 2^1 = 8$ is the expression that includes an exponent and has a value of 8

Solution:

Given that, Use the number 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8

We have to use each number only once

Given numbers are 8, 6, 2

Our expression should include exponent and the result should be 8

Among 6 and 2 we can use 2 for exponent

Raise 2 to power of 1

The expression becomes:

$6 + 2^1 = 8$

Here we have used one operation, that is addition

Verifying the expression

$6 + 2^1 = 6 + 2 = 8$

Thus the required expression is found
