Answer:
Step-by-step explanation:
Area = 0.5(base)(height)
= 0.5(12y-3)(y+1)
= 0.5(12y^2+9y-3)
= 6y^2+4.5y-1.5
The second one:
3^7 x 3^(86/10) x 3^(9/1000)
That is because when you multiply powers with the same base ( in this case they are all 3), you just leave the base as it is and add the exponents
so it is basically 3^(7 + 86/100 + 9/1000) which is 3^7.869

Answer:
1. B
2. B
Step-by-step explanation:
To find the missing term, find the scale factor between the fractions - the number which multiplies to one to make the other.
1. 7 x __ = 35
7x 5 = 35 therefore 5 is the scale factor. Multiply 15 x 5 = 75
2. 8 x ___ = 32
8 x 4 - 32 therefore the scale factor is 4. Multiply 1 x 4 = 4.
01 because it have the other side
