The answer is: I don't really know. YOU DIDN'T GIVE A SIDE SO BOW AM I SUPPOSED TO KNOW!!!!!!!!!!!!!!!!!!!!!!
You have to give a side first.
Answer:
Option C.
Step-by-step explanation:
The given table is
x f(x)
-4 0
-2 2
0 8
2 2
4 0
6 -2
A graph of a function intersect x-axis if the function contains the points whose y-coordinate is 0.
From the given table it is clear that the value of f(x) is 0 at x=-4 and x=4. It means, the continuous function intersect the x-axis at two point (-4,0) and (4,0).
Therefore, the correct option is C.
#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side
#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
Answer:
50cm²
Step-by-step explanation:
Let the width be x cm
The length will be x + 5 cm
Perimeter is 30cm
Perimeter is given by (2 × length) + ( 2 × width)
2(x + 5) + 2x = 30cm
2x + 10 + 2x = 30cm
4x = 20cm , x = 20/4 = 5cm
x (width) = 5cm
Length = 5 + 5 = 10cm
Area = Length × width
Area = 10cm × 5cm = 50cm²
