Point R is the midpoint of FE¯¯¯¯¯ , so the coordinates of point R are (3a, b).
In △DEF , the length of the base, DF¯¯¯¯¯ , is
4a, and the height is 2b, so its area is
1/2×4a×2b = 4ab.
In △QRP , the length of the base, QR¯¯¯¯¯ , is
3a-a = 2a, and the height is b, so its area is 1/2×2a×b = ab .
Comparing the expressions for the areas proves that the area of the triangle created by joining the midpoints of an isosceles triangle is one-fourth the area of the larger isosceles triangle.
hello :
<span>a=9y+3yx
y(9+3x) = a
y = a/(9+3x).......9+3x </span><span>≠ 0</span>
Answer:
yes, because anything to the 0 power is 1 so the equation would simplify to 1+1 which is equal to 2
Step-by-step explanation:
5.1 gallon per container because you just divide 40.8 with 8.
The answer is 101 and 102.
101 and 102 are back to back and 101+102=203
