Answer:
Could you post the rest of it pllease
Step-by-step explanation:
Answer:
(a)
Area: 930 meters(m)
Perimeter: 122 meters(m)
(b)
Area: 616 centimeters(cm)
Perimeter: 116 centimeters(cm)
(c)
Area: 1008 millimeters(mm)
Perimeter: 128 millimeters(mm)
Explanation:
Area = length x width
Perimeter = length+width+length+width
Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008
Perimeter for (a) is 31+30+31+30=122
Perimeter for (b) is 44+14+44+14=116
Perimeter for (c) is 36+28+36+28=128
Answer: The Answer is 72 or 7.2x10^1
This is due to 10^2 equaling 100. 100x0.72 is 72 bec you are moving the decimal point 2 to the right.
Answer: C) x = 3, (x = 2 is an extraneous solution)
<u>Step-by-step explanation:</u>
- 
= 
- = 
Restrictions: <em>Denominator cannot equal zero</em> (x - 1 ≠ 0) and (x - 2 ≠ 0), so x ≠ 1 and x ≠ 2
- 
= 
x(x - 2) - 1(x - 1) = 2x - 5
x² - 2x - x + 1 = 2x - 5
x² - 3x + 1 = 2x - 5
<u> -2x + 5</u> <u>-2x + 5 </u>
x² - 5x + 6 = 0
(x - 2)(x - 3) = 0
x - 2 = 0 x - 3 = 0
x = 2 x = 3
NOTE: x = 2 is an extraneous solution because it is one of the restricted values.
Answer:
5x-8y
Step-by-step explanation:
4x-9y+x+y
=4x+-9y+x+y
=4x+-9y+x+y
=(4x+x)+(-9y+y)
=5x+-8y
=5x-8y
