Answer:
Second option, h=(
) ft
Step-by-step explanation:
Area = Base x Height
Height = Area ÷ Base
= 
= 
(split fraction for easier simplification)
= 
ab + a + 4b+4 = a(b+1) + 4(b+1) = (b +1)(a + 4)
<span><u><em>Answer:</em></u>
(5 * 1) + (9 * 0.1).<span>
<u><em>Explanation:</em></u>
To write a number in expanded form you have each digit multiplied by its numbers place and add each digit together. 5 is in the ones place so it becomes (5 * 1).
9 is in the tenths place so it becomes (9 * 0.1).
add them together to get (5 * 1) + (9 * 0.1)</span></span>
Hey I’m in class but it is fine to help a friend so that answer is 1350
It is always isosceles because it can be proved as follows:
The perpendicular bisector dissects the triangle into two, and it is the common side. Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.
