For this case we have the following expression:

The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:

Then, doing distributive property we have:

Adding similar terms:
Answer:
The simplified expression is:
(3x-12)+12(xy-10), x=4, y=6
(3(4)-12)+12((4)(6)-10)
(12-12)+12(24-10)
0+12(14)
12*14=168
Answer:
21.46 cm squared
Step-by-step explanation:
3.8x5.8=21.46
1 penny each day = 7 pennies each week
total pennies = 161
divide 161 by 7 = 23 weeks
Answer:
784
Step-by-step explanation:
A = 1/2ap A = area , a = apothem , p = perimeter
a = 1/2s a = apothem length , s = side length
14 = 1/2s , 14(2) = 1/2s(2) , 28 = s
p = 4(s) , p = 4(28) , p = 112
A = 1/2ap , A = 1/2(14)(112) , A = 784
or
A = s^2 , A = 28^2 , A = 784
