Assuming a and b are parallel
<5 = <9 false
<1 = <12 false
<1 = <8 true
<3 = <7 true
Answer:
length = 37
Step-by-step explanation:
w= x
l= 3x + 1
to get the perimeter you need to add all sides.
x + x + 3x + 3x + 1 + 1 = 98
8x + 2 = 98
8x = 96
x = 12
To get the length plug in the value of the x to 3x + 1.
length = 3(12) +1
length = 37
1/9 or 1 divided by 9 is the answer.
Answer:
Peter ran 78 miles
Step-by-step explanation:
Step-by-step explanation:
Actually, it isn't that hard. Remember the difference of squares? (a + b)(a - b) = a² - b² and in this case 9 is a and 4x is b so our answer is 81 - 16x².
