the answer is 216.81 I looked it up on a calculator
Y=3(x+1)(x-5)
I'm going to ignore 3 for now, but will add it later.
FOIL the (x+1)(x-5)
F = multiply the First numbers x and x
O = multiply the Outside numbers x and -5
I = multiply the Inside number 1 and x
L = multiply the Last numbers 1 and -5
3(x^2 + -5x + 1x + -5)
add -5x and x
3(x^2 + -4x + -5)
multiply the numbers inside the parenthesis by 3
3x^2 + -12x + -15
Given:
The statement is:
{5, 6, 7} = {5, 5, 6, 7, 7}
To find:
Whether the given statement is true or false.
Solution:
Two sets are equal if they have exactly the same elements.
The given set {5, 6, 7} has three elements and the set {5, 5, 6, 7, 7} has five elements but we known that all the elements of a set are distinct. It means, it has no repeated element.
Set {5, 5, 6, 7, 7} has three distinct elements 5, 6, 7. So,
{5, 5, 6, 7, 7} = {5, 6, 7}
Therefore, the given statement is true.
Answer:
cost of bracelet = 25*.05 +4*.45
cost of bracelets = 2(25*.05 +4*.45)
Step-by-step explanation:
One bracelet
Supplies needed:
25 beads and 4 charms
Each bead costs .05 and each charm costs .45
Cost of bracelet = number of beads * cost per bead + number of charms * cost per charm
cost of bracelet = 25*.05 +4*.45
cost of bracelet = 1.2 +1.8
=3.00
To make 2 bracelets
Cost of bracelets =2*( number of beads * cost per bead + number of charms * cost per charm)
cost of bracelets =2*( 25*.05 +4*.45)
cost of bracelets=2( 1.2 +1.8)
cost of bracelets = 2*3
cost of bracelets = 6
