Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
Answer:
252 in²
Step-by-step explanation:
The 3 by 6 tab on the right is the same size as the 3 by 6 notch on the left
moving the tab into the notch make a perfect rectangle
The size of the rectangle will be
12 by 21
12 * 21 = 252
252 in²
1. alternate exterior
2. consecutive interior
3. alternate interior
hope this helps!!!
The answer is 9
Replace the x with the number given
Since the x is next to the 2 it meant to multiply
2(3)+3=9
