Answer:
Step-by-step explanation:
Rule Example
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6
Option A:
V = 1/3 * b^2 * h
V = 1/3 * 10.5^2 * 6
V = 1/3 * 110.25 * 6
V = 220.5
Option B:
V = 1/3 * b^2 * h
V = 1/3 * 3.6^2 * 8
V = 1/3 * 12.96 * 8
V = 34.56
Option C:
V = 1/3 * b^2 * h
V = 1/3 * 4.2^2 * 12
V = 1/3 * 17.64 * 12
V = 70.56
Option D:
V = 1/3 * b^2 * h
V = 1/3 * 6^2 * 8.4
V = 1/3 * 36 * 8.4
V = 100.8
I guess it's 'None of the Above'

Hi,
I am quite good at maths and will be happy to help you, not just in Algebra, but any other topics in maths
Answer:
4 pencils
Step-by-step explanation:
3*1.45 = 4.35 ---> spent for the pens
( 10 -[ 4.35 + 2.05] ) = money spent on pencils
0.9x= 3.6
x=3.6/0.9 = 4
A: 8*9= 72
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7
C: 7(5+9)
