Answer:
8x-9y=31
Step-by-step explanation:
11 as many fiction books as non fiction.
Fiction books F, Non Fiction NF
F: NF = 11 : 1
Total ratio 11+ 1 = 12.
Fraction of Fiction books F, = 11/12
Total books = 312.
Fiction books = 11/12 * 312 = 286
Fiction books = 286
Two sides are congruent to each other.
The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
A triangle with all sides of different lengths. All angles are different, too. So no sides are equal and no angles are equal.

Answer:
Hello! answer: 268
Step-by-step explanation:
When doing these you want to find each face separately then add them up so here are all the faces... 24 + 24 + 80 + 80 + 30 + 30 = 268 so 268 is our surface area! Hope this helps!
The area of a rectangle = (length)(width)
let's call the width x. the length is twice the width, so the length = 2x.
so the area = (x)(2x)
area = 2x^2
