II. Evaluate the following expressions. 6. 6 + 7 x 8
7. (25 + 11) x 2
8. 102 - 16 - 8
9. 3 + 6 x (5 + 4) = 3-7
10. (96 = 12) + 14 x (12 + 8) = 2
whats this plzz...​

6. 62

7. 72

8. 78

9. 57 = -4 ??

10. ??

Step-by-step explanation:

6. 7*8 = 56, 56+6 = 62

7. 25+11 = 36, 36*2 = 72

8. 102-16-8 = 78

First one is 13×8

second one is 36×2

third one is 9×9=4

forth one is I don't know

the answer is b i just did that

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
