Angel is 8 years old and Alex is 30 years old x-y=30
10:18 is an equivalent ratio.
Answer:
y=-0.078x^2+8.407x+-92.892
Step-by-step explanation:
but your x and y in desmo than go under the table do y1=ax^2 then under the 2 put a 1 than +bx1+c than you round your a b and c to the nearest thousandth than after that add a b and c then after you get your answer than but x^2 behind a than x behind b then nothing behind c hope this works for you
Step-by-step explanation:
- The area of the blue square will always equal the sum of the area of the orange and red rectangles
The pythagorian theorem:
a²+b² = c²
now let a be the side of the red triangle and b the side of the orange one
so a² is the area of the red triangle and b² is the area of the orange one
Let c be the side of the blue rectangle
so c² is the area of it
then what we concluded is right
- the hypotenuse is the blue side since it is the larger one
AB = 9 cm
BC = 6cm
CD = 7 cm
AE = 6 cm
3BC = AB
3ED = AE
AB = AE
BC ED
⁹/₃ = ⁶/ₓ
3 · 6 = 9 · x
18 = 9x
9 9
2 = x
ED = 2 cm
