I assume that you mean: the length is 7cm more than the width, and the perimeter is 74 cm.
If so, we can write down the following system, where l and w represent, respectively, the length and the width:
We can easily solve the second equation:
And finally solve for the length:
<h2>1.</h2>
So remember that with more than one pair of parentheses, you have to start from the inside and make your way outside.
Firstly, on the left side, solve 5+2 and on the right side solve 4 × 3:
Next, on the left side, solve 3 × 7 and on the right side solve the subtraction:
Lastly, solve the remaining multiplication on the left side and the answer is
<u>Since 84 is not equal to 83, the correct answer is the second option.</u>
<h2>2.</h2>For this, plug 5 into the z variable to solve.
<u>Since 15 = 15 is true, your answer is the first option.</u>
<h2>3.</h2>So for this, it's a similar process as Question 2 except that you are plugging in 0 into the x variable to solve:
<u>Since 8 = 0 is a false statement, the correct answer is the second option.</u>
