Answer:
9.5 inches width
Step-by-step explanation:
solve it using the proportion method
height/ width = 5/19
so let the width be x
so if height: width:: height: width
5 : 19 :: 2.5 : x
product of extremes = product of means
5 x x = 19 x 2.5
x= 47.5/5
x= 9.5 inches (width )
Answer:
C. √3
Step-by-step explanation:
When one of the factors is a rational number (0.5), the product will be irrational if, and only if, the other factor is irrational.
Of the numbers offered, only √3 is irrational.
√3 will produce an irrational product when multiplied by 0.5.
__
The other values are all rational:
A: 4
B: 5/9
D: 1/3
FOIL method : F = First , O = Outer , I = Inner, L = Last
(6x-6)(x+6)
First: 6x * x = 6x^2
Outer: 6x * 6 = 36x
Inner: -6 * x = -6x
Last: -6 *6 = -36
Put these in order and we get : 6x^2 + 36x -6x -36
The distributive property combines like terms.
