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

so

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

Simplify x^3 y^3 / x^3 y^3
Marysya12 [62]

Answer:

\frac{1}{y}

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

\frac{x*x*x*y*y*y}{x*x*x*y*y}

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is \frac{1}{y}

Malcolm is filling bags with rice. He starts with a 5 1/4 pound container of rice and fills each
Sliva [168]

Basically we want to know how many times 5/8 goes into 5 1/4.

5 1/4 ÷ 5/8 = 21/4 ÷ 5/8 = 21/4 × 8/5 = 42/5 = 8.4 bags

Since we cannot have a fraction of a bag, he can fill 8 bags completely.

answer: 8 bags
