Answer:
option A and E
Step-by-step explanation:
Option A is equivalent because of the commutative law of addition;
(A + B) + C = A + (B + C)
option E is also correct because multiplication rule of inside the brackets.
A - ( - B - C) = A + B + C
The ratio of the park's length and width is 300/240=5/4
if he takes the length as 10in then the width should be 8in,
so it's area should be 80in²
Answer: 5 meters
Step-by-step explanation: 1/2 = .5, if you move the decimal in front of the 5, you would go from .5 to 5
Its depends on what you are working on
Answer:
you solve these by plugging the numbers into pythagorean theorem which is
a^2 + b^2 = c^2 (a squared plus b squared equal c squared)
C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)
so 17 would be 9.5^2 + 3.8^2 = c^2
So 90.25 + 14.44 = c^2
104.69=c^2
Then to solve for c take the square root of each side and get
10.23=c
To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it
