Answer:
<h3>
EVEN</h3>
Step-by-step explanation:
the product of odd numbers is always odd
the product of even numbers is always even
the product of odd number and even one is always even
the <u>sum of two odd </u>numbers is always <u>even</u>
and the sum of two even numbers is always even
so if x is even number we have:
x²=x•x - even number
x⁴=x²•x² - even number
3x²=3•x² - even number
y = x⁴+3x² <u>- even number</u>
and if x is odd number we have:
x²=x•x - odd number
x⁴=x²•x² - odd number
3x²=3•x² - odd number
y = x⁴+3x² <u>- even number</u>
Answer:
Width = 13 Length = 15
Step-by-step explanation:
2+w=l
w+w+2+w+2+w=56

1
Step-by-step explanation:
nxp= -5 x -2 (negative times a negative is positive) -5 x -2= 10 m/10=10/10 = 1
Answer:
b > 250/9 and w ≥ 0
Step-by-step explanation:
7/9 (b - 27) > 49/81
First, simplify both sides of the inequality:
7/9b - 21 > 49/81
Add 21 to both sides
7/9b - 21 +21 > 49/81 +21
Multiply both sides by 9/7
9/7 x 7/9b > 49/81 x 9/7
b > 1750/81
Simplify
b > 250/9
11w - 8w ≥ 14w
Simplify both sides once again
3w ≥ 14w
Subtract 14w from both sides
3w - 14w ≥ 14w - 14w
-11w ≥ 0
Divide both sides by -11w
w ≥ 0
Answer: 212 7/20
Step-by-step explanation: We know that 212 is the whole number. So we need to convert .35 into a fraction in simplest form. Any decimal that has a hundredths place will be divided by 100 to get the fraction. In this case that fraction would be 35/100. And to convert that into simplest form, you need to find the least (or lowest) common denominator which is 5. Then you divide the numerator and denominator by 5 and get 7/20, so your answer is 212 7/20
