Solve by Elimination.
multiply the second equation by -3.
Add the Equations.
Plug this back in one of the equations.
No, Abe is incorrect.
If you don’t know which side is the hypotenuse, you have to try every possibility.
3^ + 4^ = 5^
25 = 25
The triangle is a right triangle. The side which is 5 cm long is the hypotenuse.
Answer:
The area that she painted = 896 mm^2
Step-by-step explanation:
Given:
The given figure is a pyramid with square base.
Here we need to find the surface area of the figure that need to be painted.
Surface area of a square pyramid = (S×S) + 2×S×L square.units
Where, S = side of the base L = slant height of the pyramid.
Now we have to plug in the given values.
Here S = 14, L =25
Plug in these values into the formula
= (14*14) + 2*14*25
= 196 + 700
= 896 mm^2
The area that she painted = 896 mm^2
Hope this will helpful.
Thank you.
