Answer:
Correct option: second one
Step-by-step explanation:
Let's check each option to find the correct one.
First option: x and y increase by 2.3 times, so the figure expands. So this is not the correct option.
Second option: x and y decrease 0.52 times, so the figure is reduced. So this is the correct option.
Third option: x and y are translated by 1/3 of their position, so the figure is not reduced.
Fourth option: x and y increase by 7/2 times, so the figure expands. So this is not the correct option.
Correct option: second one
Answer:
X is 2
Step-by-step explanation:
4 - 1 is 3
-10 + 13 is 3
To find the area of a triangle, the formula is
=A
Since you have the area and the base you can replace the variables and place the numbers into its place.
17.5 =
From here you need to solve for h by first multiplying the (1/2) and 7 which would equal 7/2 or 3.5
Then you would have
17.5 = 3.5(h)
Now you divide both sides by 3.5 which would make h equal to
h=5
Double check and do
which would equal to
All of that equals to 17.5, which is the correct answer so the height is 5m.
Answer:
22.13 units
Step-by-step explanation:
P(ABCD) = AB + BC + CD +AD
- P = √(AF²+FB²) + 3 + √(CE²+DE²) + 9
- P = √(4²+4²) + √(4²+2²) + 12
- P = √32 + √20 + 12
- P = 4√2 + 2√5 + 12
- P = 5.66 + 4.47 + 12
- P = 22.13 units
