Gemiola [76]

Answer:

BC=25

Step-by-step explanation:

this is an isosceles triangle, so sides AB and sides AC are equal

AB = AC

4x+1 = 2x+23

subtract 2x from each side

2x+1 = 23

subtract 1 from each side

2x =22

divide by 2 on each side

x =11

BC = 3x-8

substitute the value of x

BC = 3*11 -8

BC = 33 -8

BC=25

The quantity a varies directly with b and c and inversely with d. The quantity d is tripled. Which of the following must be true

Vinvika [58]

Lets name the quantity Q
$Q=k* \frac{b*c}{d} 

When quantity d is tripled, we get




$
$Q=k \frac{b*c}{3d} 

To be the relationship the same, we see that we need to$ $
multiply /numerator / by /3 


$ $Q = k \frac{3bc}{3d} 

So the answer should be 
"The product of c and b must be tripled."$
