Step-by-step explanation:
If you have to make a 48 foot long fence and each post is 6 feet then you would need 8. 6 times 8 =48
Answer:
x = - 3, x = 2
Step-by-step explanation:
Since x = 1 is a zero then (x - 1) is a factor of the polynomial
dividing x³ - 7x + 6 ÷ (x - 1)
= (x - 1)(x² + x - 6)
= (x - 1)(x + 3)(x - 2)
equating (x + 3)(x - 2) = 0 gives the other zeros
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
All you have to do is use the formula and where it says x just full in the number
Answer:
8 1/8 inches
Step-by-step explanation:
P = 2 ( l+w)
l = 13 1/8
P = 42 1/2
Substitute the two values into the equation
42 1/2 = 2 ( 13 1/8 + w)
Change the mixed numbers to improper fractions
42 1/2 = ( 2 *42+1)/2 = 85/2
13 1/8 = ( 8*13+1) /8 =105/8
85/2= 2 (105/8+ w)
Divide each side by 2
85/2 *1/2= 2/2 (105/8+ w)
85/4 = (105/8+ w)
Subtract 105/8 from each side
85/4 -105/8 = (105/8-105/8+ w)
Get a common denominator
170/8 -105/8 = w
65/8 = w
Change back to a mixed number
64/8 + 1/8 = w
8 1/8
Answer:
See below.
Step-by-step explanation:
A(1, 4)
B(3, 0)
C(-3, -2)
We find the coordinates of he midpoints using the midpioint formula.
D([1 + 3]/2, [4 + 0]/2) = D(2, 2)
E([1 + (-3)]/2, [4 + (-2)]/2) = E(-1, 1)
We find the slopes using the slope formula.
slope of BC:
m_BC = (-2 - 0)/(-3 - 3) = -2/(-6) = 1/3
slope of DE:
m_DE = (1 - 2)/(-1 - 2) = -1/(-3) = 1/3
Since the slopes of BC and DE are equal, the lines are parallel.
