D. (9x-4)^2
You can get this by taking the square roots of the outside terms. Then multiply them together and then by 2. For this you should get the middle term.
Answer:
ED: 6.5 cm BE = 14.4 cm
Step-by-step explanation:
Add 20 and 5 to get side AC.
25/20 gives us the scale factor to go from 25 triangle ABE to triangle ACD.
Multiply 26 by the SF to get AD.
Subtract length of AD by AE to get ED. You should get 6.5 cm (don't forget units!!!!)
To go from triangle ACD to triangle ABE, we can do 20/25 to get the scale factor.
Using that number, multiply it with 18 to get BE.
The answer should be 14.4 cm.
This is possible because the two triangles ACD and ABE are similar via the angle angle angle similarity theorem depicted in my screenshot.
Answer:
227.2727 kilograms
Step-by-step explanation:
The tiger weight is 550 pounds, and we want to convert this value to kilograms, so we need to use the ratio between pounds and kilograms.
We know that 1 kilogram is equal to 2.2 pounds, so we can solve this problem using a rule of three:
1 kilogram is equal to 2.2 pounds,
X kilograms are equal to 550 pounds.
1/X = 2.2/500
X = 500/2.2 = 227.2727 kilograms
So the weight of the tiger in kilograms is 227.2727 kilograms.

2) B. 25 cm ^2The area of a regular pentagon can be found using the formula.
s=side length
A≈960 square feet
The apothem of a square is half of the side length. 2.5*2=5. 5^2 = 25cm^2
Is 63 degrees an option? Cause that’s what I got. That’s a scalene triangle, none of the sides are equal, they add up to 180 degrees. So add the 2 numbers you have together and you get 117. Subtract 117 from 180 and you get 63
