Answer:Triangle A = 7.5 Triangle B= 15 Area=22.5
Step-by-step explanation:
So first we have to get the area of Triangle A. This means we have to find the height and base of it. The base is 5 and the height is 3 as you can see in the picture. So 5x3 equals 15, but because it's a triangle we have to divide by 1/2, which makes 7.5. So the area for Triangle A is 7.5.
Now we have to find the area for Triangle B. The height is 3 and the base is 10. So like we did with Triangle A we have to multiply and then divide by 1/2. Which makes 15.
Now that you have both areas you just have to add them together. Which makes 22.5.
So 22.5 is the answer. Give brainilest if you can!

Answer:
x = ±5
Step-by-step explanation:
x^2-25=0
Add 25 to each side
x^2-25+25=0+25
x^2 = 25
Take the square root of each side
sqrt(x^2) = sqrt(25)
x = ±5
