The proportion equal to a/b = c/d is A.) A/C = B/D
We will know if a proportion is equivalent when its cross products are equal.
a/b = c/d where ad = bc
since ad = bc, a/c = b/d
1. Do they match? No
How do you know? When substituted y = 3(2) - 4 is 2
y = 3(4) - 4 is 8
y = 3(8) - 4 is 20 not 14. So the table isn’t fully correct.
2. Do they match? No
How do you know? Because it says she walks UP the stairs not down. So -2 doesn’t make sense.
3. Do they match? Yes
How do you know? 0 means that the pile didn’t start with 6 so when you add 3 to 0, it’s 3. (duh lol)
On day 1, it starts with 6, (1)(6) = 6, and then they added 3 rocks, so it’s 9.
Day 2, twice as many rocks, so it starts with 12 now. + 3 is 15.
Day 3 starts with 18 rocks now. + 3 is 21.
Answer:
A = 35 square units
Step-by-step explanation:
Formula to calculate the distance between two points and is,
d =
Length of the segment between A(2, 2) and B(9, 2) =
= 7 units
Length of the segment between B(9, 2) and C(9, -3) =
= 5 units
Length of the segment between C(9, -3) and D(2, -3) =
= 7 units
Length of the segment between A(2, 2) and D(2, -3) =
= 5 units
Therefore, given polygon is a rectangle.
Area of the rectangle = length × width
= 7 × 5
= 35 square units
