AB = x + 15 DC = 4x AD = x + 10 BC = ? Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent. Show

dexar [7]

Answer:

$BC=15\ units$

Step-by-step explanation:

we know that

In a parallelogram opposite sides are congruent

In this problem

we have that

AB and DC are opposite sides

AD and BC are opposite sides

AB=DC

AD=BC

step 1

Find the value of x

AB=DC

substitute the given values

$x+15=4x$

solve for x

$4x-x=15$

$3x=15$

$x=5\ units$

step 2

Find the length of AD

we have that

$AD=x+10$

substitute the value of x

$AD=5+10=15\ units$

step 3

Find the length of BC

Remember that

AD=BC ----> by opposite sides

therefore

$BC=15\ units$

Decrease £120 by 15%

Irina-Kira [14]

To decrease this amount by 15% we must first find out what is 15% percent.

We can do that by multiplying the decimal of 15% by 120

15% = 0.15

0.15 x 120 = 18

So 18 is 15% of 120.

Wait! that's not the answer. We are asked to decrease by 15%

So 120 - 18 = 102

Your answer is £102
