I hope this helps
Answer:
29 m
Step-by-step explanation:
The dashes mean that the lines are equal in length, so from this we can determine that the area marked 441 m² is a square.
Area of a square = x², where x is the length of 1 side.
Therefore, x = √441 = 21 m
Now we have a right-angled triangle with two legs of 20 m and 21 m. We need to find the hypotenuse (labelled ?). To do this, use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse.
Therefore,
20² + 21² = c²
⇒ 400 + 441 = c²
⇒ 841 = c²
⇒ c = √841
⇒ c = 29
So the side marked ? on the diagram is 29
Reflections across the x-axis leaves the x coordinates the same but the y coordinates change sign
so point P (2,-12) is reflected to (2, 12)
So now you can identify the correct choice
Answer:
B) 8
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept.
Answer:
perimeter: 8a³b+4ab
area: 4a²b²
Step-by-step explanation:
2a³b + 6a³b+4ab=
8a³b+4ab
1/2×4ab×2a³b=
4aa³bb
4a⁴b²
