Answer:
x = 144
Step-by-step explanation:
y α x
we introduce a constant 'k' when changing from α to =.
i.e y = kx
y = ⅓ when x = 12
Meaning, ⅓ = k * 12
⅓ = 12k
k = ⅓ ÷ 12
k = 1/36
If y = 4, x = ?
using the equation y = kx
4 = (1/36)x
x = 4 ÷ (1/36)
x = 4 * 36
x = 144
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.
Answer:
12 x 3 = 36 + 33
Step-by-step explanation:
sorry if it's wrong but the answer to the equation i put out would be 69
SA = 2lw + 2lh + 2hw
SA = 2(15)(2) + 2(15)(6) + 2(6)(2)
SA = 60 + 180 + 24
SA = 264
