4.5 ÷ 3 = 1.5
This means that the ratio has increased by 1.5
Since anything multiplied on one side of a ratio has to be multiplied on the other side too, we multiply 1.5 by 4:
1.5 X 4 = 6
The width would be 6cm
Step-by-step explanation:
<B is the right angle
<A is acute
<C is acute
<D is obtuse
Answer:
x1 = 2 -
x2= 2 +
Step-by-step explanation:
x/4 + 6 = 7 + 1/4x
(x^2 - 1)/4x = 1
x^2 - 1 = 4x
x^2 - 4x -1 = 0
x= (4+
)/2 = 2 -
x= 2 +
84/60=1.4
210/1.4=150
The answer is 150 cm
