Use a proportion if two cassettes cost $14.50 How much will 15 cost

1 answer:

8 0

Cost/(number of cassettes) = $14.50/2 = x/15

Multiply by 15 to solve
15*($14.50/2) = x = $108.75

15 cassettes will cost $108.75.

Answer:

x²+8x+16

Step-by-step explanation:

f(x) = (x+4)²

= (x+4)(x+4)

Find side AB 14() 24() 33() 40()

Ahat [919]

Answer:

$AB=DC=32\ units$

$AD=BC=24\ units$

Step-by-step explanation:

we know that

In a parallelogram, opposite sides are parallel and congruent

In this problem we have a parallelogram

$DC=AB$

$AD=BC$

substitute the given values

$5x-18=2x+12$

$5x-2x=12+18$

$3x=30$

$x=10$

Find the length of side AB

$AB=2x+12$

substitute the value of x

$AB=2(10)+12=32\ units$

Find the length of side CB

$BC=3x-6$

substitute the value of x

$BC=3(10)-6=24\ units$

therefore

$AB=DC=32\ units$

$AD=BC=24\ units$
