Answer:
0.25 and 0.50
Step-by-step explanation:
The base is 16 inches.
The formula for the area of a triangle is
A = 1/2bh
We know that b = h+5, so we can rewrite this as:
A = 1/2(h+5)(h)
Using the area that we have, we now have:
88 = 1/2(h+5)(h)
We can cancel the 1/2 by multiplying by 2:
88*2 = (1/2)(h+5)(h)*2
176 = (h+5)(h)
Using the distributive property, we have:
176 = h² + 5h
We want quadratic equations to be set equal to 0, so we will subtract 176 from both sides:
176 - 176 = h² + 5h - 176
0 = h² + 5h - 176
Using the quadratic formula:
Since a negative length makes no sense, we know that h=11.
The base is 5 inches longer than the height, so b = 11+5 = 16.
Solution: 1,-3)
Hope this helps
Answer:
Step-by-step explanation:
It is a right angle triangle with height and base = 3. The 4.24, for area, is not relevant.
Area = h * b / 2
Area = 3 * 3/2
Area = 9/2
Area = 4.5
2.25+5.50, 2.50+5.25, 3.49+4.26, etc.
