The answer is A: 4/3=DE/9
4 is corresponding to line DE
3 is corresponding to 9
Answer:
The area of the shape is 122.30 cm^2
Step-by-step explanation:
To calculate the surface area, we identify the side shapes
We have this as;
a rectangle that measures 11 cm by 3 cm, a rectangle that measures 3 cm by 6 cm, a rectangle that measures 8 cm by 3 cm, 2 triangles ( base and top) that has a height of 4.3 cm and a base of 11 cm
The area of the rectangles is simply the product of the side lengths
The area of the triangles is the product of the base and the height divided by 2; but since we have 2 exact triangles, we can simply multiply the base and the height to serve as the area of both
Thus, we have the area of the shape as follows;
(11 * 3) + (3 * 6) + (8 * 3) + (4.3 * 11)
= 33 + 18 * 24 + 47.3
= 122.30 cm^2
The answer you are looking for is x - 1.
To find this answer you divide 5x by 5x, to get 1x or x. Then, you divide 15 by -15 to get -1. Thus meaning the answer is x - 1.
I hope this helps!
Answer:
4.8 dollars for 1 pound super nutty
Step-by-step explanation:
if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
in terms of this example :
AP × BP = CP × PD
(5+7) × 7 = (14 + PD) × PD
12×7 = 14×PD + PD²
84 = 14×PD + PD²
PD² + 14×PD - 84 = 0
this quadratic equation can be solved by this generic formula :
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = PD
a = 1
b = 14
c = -84
PD = (-14 ± sqrt(196 - 4×1×-84))/(2×1) =
= (-14 ± sqrt(196 + 336))/2 = (-14 ± sqrt(532))/2 =
= (-14 ± sqrt(4×133))/2 = (-14 ± 2×sqrt(133))/2 =
= -7 ± sqrt(133)
PD1 = -7 + sqrt(133) = 4.532562595...
PD2 = -7 - sqrt(133) that is negative and does not make sense for a distance.
I don't know the format you need to have the answer in,
but it is in value
4.532562595... or -7 + sqrt(133)
