So if the ratio is 2:3, then the younger child would represent the 2. so it would be 2:3 is 4:x. Thereby, the answer would be 6, because of proportions. To check, simplify 4:6, and you would get 2:3.
Answer:
2x^2 + 8x - 24
Step-by-step explanation:
The formula for a trpezoid is (b1+b2)*h/2. If you substitute with the given domensions, you get
((2x + 12 + 4)*2x-4)/2
Simplify
((2x+16)*2x-4)/2
(4x^2+16x-48)/2
2x^2 + 8x - 24
For Tia's wire we calculate, the wire is 4 meter and 8 centimeter long, that is to say 408 centimeter long total, and it is divided in 10 pieces, so we do:
tia = 408/10 = 40.8 cm
That is to say that Tia's wire pieces are <span>40.8 cm long
For Marta's wire, it is 540 centimeter long and is divided into 9 pieces, that is:
marta = 540/9 = 60 cm
Then Marta's wires are longer than those from Tia's, let's see for how much:
marta - tia = 60 - 40.8 = 19.2
therefore, Marta's wires are longer than Tia's wires for 19.2 cm
