Answer:
13 , 17 and 25 cm.
Step-by-step explanation:
Let the length of the first side be x cm.
Then the second is x+4 and the third is 2x-1 cm long.
As the perimeter = 55 cm we have the equation:
x + x + 4 + 2x - 1 = 55
4x + 3 = 55
4x = 52
x = 13 cm.
Easy.
212.8 divided by 3.8 is equivilant to 56. You would solve this by working a long division equation. Please give brainliest, I really need virtuoso.
Answer:
y=(x-2)²+2
Step-by-step explanation:
y=x²-4x+6 (a=1 , b=-4 , c=4)
vertex form : y=a(x-h)²+k
h and k are the vertex coordinate :
h=-b/2a =-4/-2
h=2
find f(2) to find k in the equation :x²-4x+6
(2)²-4(2)+6
4-8+6=2 (k=2)
vertex form : y=a(x-h)²+k (a=1)
y=(x-2)²+2
The coordinates of point D is given as
Since the question asks to get two points sharing the same x-coordinate as D, we will move the points along the y-axis.
Therefore, we will add and subtract 7 units from the y-axis.
Let the first point be A. The coordinates for A will be
Let the second point be B. The coordinates will be
We can plot the graph as shown below:
If you have a discount on an item..
ex. 15% off coupon for $20 shirt
20 x 0.15= $3 <--- 15% of 20
20-3=$17 <--- final price of shirt after coupon
