The combined area of two squares is 45 square centimeter each side of one square is twice as long as the side of another square

Roman55 [17]

Let $x$ be the side length of the small square. Then, the side length of the big square is $2x$ .

The respective areas are $x^2$ and $(2x)^2=4x^2$

So, the sum of the areas are $x^2+4x^2=5x^2$

We have

$5x^2=45 \iff x^2=9 \iff x=\pm 3$

We can't have negative lengts, so we choose $x=3$

So, the side length of the larger square is 6.

C an anyone solve this 3(2b + 3)2 = 36<br> and if so what is it

Natali [406]

$3(2b + 3)^2 = 36$

Divide by 3 on both sides:
$(2b + 3)^2 = 12$

Square root both sides:
$2b + 3= \pm \sqrt{12}$

Take away 3 from both sides:
$2b= \pm \sqrt{12} - 3$

Divide by 2 on both sides:
$b= \dfrac{ \sqrt{12} -3 }{2} \ or \ b= \dfrac{ -\sqrt{12} -3 }{2}$

Answer:
$b= 0.23 \ or \ -3.23$

The library has 2,000 books for sale.The books are sorted into nonfiction, fiction, and children's books. The children's books n

beks73 [17]

If you take 2000 and subtract that by 500 for the childrens books that would equal 1500. So, the fiction and nonfiction books sum would have to be 1500. Since 850 plus 650 equals 1500, there would be 650 nonfiction books, 850 fiction books, and 500 children's books.

Hope This Helps!
