The value of (-12) . 8 is -96 and the value of 14.(-5).(-11) is 770
<h3>How to solve the expressions?</h3>
The question implies that we calculate the expressions in two different ways.
<u>1) (-12).8</u>
<u>Way 1:</u>
We have:
(-12).8
This means
(-12) . 8 = -12 * 8
Evaluate
(-12) . 8 = -96
<u>Way 2</u>
We have:
(-12).8
This means
(-12) . 8 = -12 * 8
Express 8 as 4 + 4
(-12) . 8 = -12 * (4 + 4)
Expand
(-12) . 8 = -12 * 4 -12 * 4
Evaluate the products
(-12) . 8 = -48 - 48
Evaluate the sum
(-12) . 8 = -96
Hence, the value of (-12) . 8 is -96
<u>2) 14.(-5).(-11)</u>
<u>Way 1:</u>
We have:
14.(-5).(-11)
This means
14.(-5).(-11) = 14 * -5 * -11
Evaluate
14.(-5).(-11) = 770
<u>Way 2</u>
We have:
14.(-5).(-11)
This means
14.(-5).(-11) = 14 * -5 * -11
Multiply -5 and -11
14.(-5).(-11) = 14 * 55
Multiply 14 and 55
14.(-5).(-11) = 770
Hence, the value of 14.(-5).(-11) is 770

First, u multiply 8x3. Only the 4 can go in the ones place so put the four beneath the line and put the 2 over the 7.
Multiply 8x7 and add 2.
Move to the tens place, do 2x3 then 2x7.
Add the products and put the comma. Then ur done
1.36 < sqrt(2) < 2.45
1.65 < sqrt(3) < 2.34
1.65 < sqrt(4) < 2.34
1.65 < sqrt(5) < 2.34
1.53 < sqrt(6) < 2.46
feel like several of these are wrong sorry
Yes, you are right, you need to flip the second fraction:
Answer:
k=99
Step-by-step explanation:
k/9 + 7 = 18
Subtract 7 from each side
k/9 +7-7 = 18-7
k/9 = 11
Multiply each side by 9
k/9 *9 = 11 *9
k = 99
