(3*4)*4 - 4 rectangles 3 by 4, and (4*4)*2 - 2 squares 4 by 4
altogether
(3*4)*4+(4*4)*2=12*4+16*2=48+32=80
Answer:
6,000
Step-by-step explanation:
500x12
34x25=850
25x10=250
36x1=36
850+250+36=1136
$11.36 or 95 coins
1a. Y = mx + b
Y = 2x + b
-2 = 2(5) + b
-2 = 10 + b, b = 12
Equation: y = 2x + 12
1b. Standard form: Ax + By = C
subtract 12 and y from both sides
2x - y = -12
Equation: 2x - y = -12
