Answer:
if you want to find perimeter you must do addition for the corners. For example on long side in the regtangle the number is 4. And the short side is 6. The one thing we must do is addition. Than the answer will be 10. You're welcome.
C) 7g - 3=42
All the other ones give the correct value of g except 7g-3=42 because the value of g is 9.

Question 5) A and C are negative effects of fossil fuels usage
Question 6) starts - 1, 5, 2, 3, 4
Step-by-step explanation:
(I) A number which can be expressed in the form m/n, where m and n are integers and n is not equal to zero, is called a <u>Rational</u><u> Number</u><u> </u> .
(ii) If the integers m and n have no common divisor other than 1 and n is positive, then the rational number m/n is said to be in the <u>Simplest</u><u> form</u><u> </u>.
(iii) Two rational numbers are said to be equal, if they have the same <u>Simplest</u><u> </u><u>form </u><u>.</u>
(iv) If m is a common divisor of x and y, then x/y = (x ÷ k)/<u>(</u><u> </u><u>y </u><u>÷</u><u> </u><u>k)</u><u> </u> .
(v) The standard form of -1 is <u>-</u><u>1</u><u>/</u><u>1</u><u> </u>
(vi) If m/n is a rational number, then n cannot be <u>0</u><u> </u>
(vii) Two rational numbers with different numerators are equal, if their numerators are in the same <u>ratio </u>as their denominators.
