Answer:
Polynomial equation is x² - 16
Her pay if x = 12 is $128
Step-by-step explanation:
This week, Kyara worked x + 4 hours
She is paid x - 4 dollars per hour
She earned (x + 4)(x - 4) = x² - 16 dollars this week
Her pay if x - 12 is;
12² - 16 = $128
<em><u>Solution:</u></em>
Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project
To find: Board that was left
From given,
Remaining feet of board is found by finding the difference between total length of board and foot that was cut off
Substituting the values we get,
Thus 
feet board is left
answer:
1
Step-by-step explanation:
#'s between zero and two = one
the only number between 0 and two is 1
x = 1 y = 1 z = 1
the average value of the sum of the squares of x, y and z = 1
1, 1, 1
the average is 1
Answer:
The dimensions of the rectangle:
length: 12cm
width: 15 cm
Step-by-step explanation:
The perimeter of a rectangle is:
perimeter = 2(length+width)
54 = 2(a+b)
a = b - 3
a = legth
b = width
then:
54 = 2((b-3)+b)
54/2 = b-3 + b
27 = 2b - 3
27 + 3 = 2b
30 = 2b
b = 30/2
b = 15
a = b-3
a = 15 - 3
a = 12
Check:
54 = 2(15+12)
54 = 2*27
