Answer:

a=3,b=1

Step-by-step explanation:

In a parallelogram opposite sides are equal/congruent.

Using this, we know that 3a-4=a+2 and b+1=2b

1st equation:

3a-4=a+2

-a -a

2a-4=2

+4 +4

2a=6

a=3

2nd equation:

b+1=2b

-b -b

b=1

a=3, b=1

X=7w^+4w-6 and y=w^-11w+13

aleksandr82 [10.1K]

Although the terms might seem intimidating, this is a simple substitution problem.

X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7

Final Answer: 8w^2 - 7w + 7

If the area of a rectangle is 10in^2, the length (2+sqrt(2))in. What is the width?

pychu [463]

Area=length times width
area=10
length=2+√2
width=w

10=(2+√2)(w)
divide both sides by (2+√2)
$\frac{10}{2+ \sqrt{2} } =w$
if we were to rationalize the dnomenator
multiply by $\frac{2- \sqrt{2} }{2- \sqrt{2} }$
$\frac{10(2- \sqrt{2})}{4-2 } =w$
$\frac{20- 10\sqrt{2}}{2} =w$
$10- 5\sqrt{2} =w$

the width is 10-5√2 m

Solution

Anit [1.1K]

Answer:

28.26658805 (I included every digit in case your teacher needs you to round)

Step-by-step explanation:

In order to find x, we need to isolate x by subtracting 15^2 and taking the square root of both sides.

Thus, we have:

$15^2+x^2=32^2\\x^2=32^2-15^2\\\sqrt{x^2} =\sqrt{(32^2-15^2)} \\\sqrt{x^2}=\sqrt{799} \\x=28.26658805$
