Answer:
(3a + 2)(a + 3)
Step-by-step explanation:
We are asked to express the diagonal of a rectangle in terms of the width in which the area of the polygon is equal to 13 square feet. The area of teh rectangle is equal to length times width. That is 13 = lw; diagonal using pythagorean theorem is sqrt ( l2 + w2). Thus d = sqrt ( (13/w)2 + w2) = sqrt ( (169/w2 + w2) = sqrt ( (169 + w4)/w2) = 1/w sqrt (169 + w4)
Answer:
1 : 8
Step-by-step explanation:
For similar figures with ratio of sides = a : b
Then ratio of areas = a² : b² and
ratio of volumes = a³ : b³
Given ratio of areas = 1 : 4
linear ratio = 
: 
= 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8
First: Find out how many of Jolie's balls are blue.
300 * 35% = 300 * 0.35 = 105 blue balls.
Second: Find the difference between the total number of balls and the blue balls to find out how many green balls Jolie has.
300 - 105 = 195 green balls.
