5 1/8 8 goes into 41 5 times with 1 left over
1. x² - 6x + 8
4*2 equals 8 and if you add 4 and 2 it gives you 6
-4-2= -6
=(x-4)(x-2)
3. the answer is A
if you plug in the points into the equation y=x
y= 1/2x + 4
given point: (4,6) x=4 y=6
6= 1/2(4)+4
6=6
Answer:
666.6667 feet²
Step-by-step explanation:
So.
Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.
Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.
So it's 8000in²
Then we do 8000 in to feet.
Which is ≈ 666.6667feet
btw it asked for feet so we give them FEET
Answer:
Step-by-step explanation:
Let the larger number is a and the smaller number is b.
According to the question,
a² + b² = 100 .... (1)
And
a² = a (4b + 8a)
a = 4b + 8a
b = -7a/4 ..... (2)
Put in equation (1)
65a² = 100 x 16
Put in equation (2)
Answer:
y = - 0.5
