Un aerodeslizador despega de una plataforma. Su altura (en metros), xxx segundos después del despegue, está modelada por:
h(x)=-2x^2+20x+48h(x)=−2x
2
+20x+48h, left parenthesis, x, right parenthesis, equals, minus, 2, x, squared, plus, 20, x, plus, 48
¿Cuál es la altura máxima que alcanza el aerodeslizador?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
