Cups: servings
8 : 22 :: x : 3
Product of means = product of extremes
22*x = 3*8
Answer:
A pair of vertically opposite angles are always equal to each other.
Answer:
Perímetro = 8.925 metros
Step-by-step explanation:
La formula del perímetro de un rectángulo es:
perímetro = 2(ancho + largo)
en este caso:
p = 2(a+b)
a = 3b/4
b = 2.55m
a = ancho del rectángulo
b = largo del rectángulo
entonces:
sustituyendo el valor de la segunda ecuación
p = 2((3b/4)+b)
p = 2((3b/4)+(4b/4))
p = 2(7b/4)
p = 14b/4
p = 7b/2
p = 7*2.55/2
p = 8.925m
Answer:
A| 12, 3
Step-by-step explanation:
The polynomial can be factored by looking for factors of 36 that sum to -15. The sum being negative while the product is positive means both factors will be negative. The answer choices suggest ...
y = (x -12)(x -3)
A quick check shows this product is ...
y = x^2 -12x -3x +36 = x^2 -15x +36 . . . . as required
The factors are zero when x is either 12 or 3.
The zeros of the equation are 12 and 3.
____
Once you realize the constants in the binomial factors both have a negative sign, you can immediately choose the correct answer (A).
Or, you can use Descartes' rule of signs, which tells you that the two sign changes in the coefficients (+-+) mean there are 2 positive real roots.
