Answer:
S=261
Step-by-step explanation:
S= 2 ( lw + wh + lh ) ............. equation 1
Given is
L = 15 inch
W= 12 inch
H = 3 inch
putting the values in equation 1
S= 15*12+ 12*3+ 15*3
S= 180+36+45
S=261
2(4-16) - (-30)
= 2(-12) -(-30)
= 24 - (-30) ....Error right here....a negative multiplies a positive = negative (= -24 + 30)
= 24 + 30
= 54
Correct:
2(4-16) - (-30)
= 2(-12) -(-30)
= -24 - (-30)
= -24 + 30
= 6
1/3
There are six lines. 1/6, 2/6, 3/6, 4/6, 5/6, and 6/6. 6/6 is 1, the last line.
Point A is at 2/6. Since both numbers can be reduced by 2, you divide them both by 2. The final answer would be 1/3.
