Answer:
The perimeter of the image is 144 inches
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
so
The perimeter of the image is equal to the perimeter of the pre-image multiplied by the scale factor
Answer:
im pretty sure its 6 x 4 sry if wrong
9x^2 - 16x + 60
Find the discriminant, b^2 - 4ac, which is the same as the value of the radicand.
(-16)^2 - 4 * 9 * 60 = -1904
Since the discriminant is negative, there will be NO real solutions, and 2 complex solutions.
Part B.
4x^2 + 8x - 5 = 0
You can tell if a quadratic is factorable if you find the discriminant and it is a perfect square. The discriminant for this quadratic is 144 so it is factorable.
(2x + 5)(2x - 1) = 0
Set each factor equal to zero.
2x + 5 = 0 2x - 1 = 0
subt 5 from both sides add 1 to both sides
2x = -5 2x = 1
divide both sides by 2 divide both sides by 2
x = -5/2 <span> </span> x = 1/2
To find this, divide 0.84 by 0.28 to get the number of pencils per ounce
The answer is 3
Answer:
710,000
Step-by-step explanation:
if you are rounding to the nearest 10,000 the only number that matters is the 1,000 number
719,000 rounded to the nearest 10,000 number is 720,000
if the number in the 1,000 place is five or above you round up and if the number is lower than five you round down
