Answer:
<em>Hello.</em>
An expression does not have an equal sign in it. Here are three examples:
2x + 7y + 6
x + 3y - 6
4x/4y x 6 Good luck!
<u><em>Answer:</em></u>
35 square units
<u><em>Explanation:</em></u>
<u>Area of parallelogram is calculated as follows:</u>
Area = base * height square units
<u>In the given question, we have:</u>
base = 5 units
height = 7 units
<u>Substitute with the givens in the above equation to get the area:</u>
Area of parallelogram = 5 * 7 = 35 square units
Hope this helps :)
Answer:
c) x = 11
Step-by-step explanation:
Given equation: 7x - 9 = 28 + 4(x - 1)
<u><em>Steps:</em></u>
1. Distribute 4 through the parentheses:
7x - 9 = 28 + 4(x) + 4(-1)
7x - 9 = 28 + 4x - 4 [simplify]
7x - 9 = 24 + 4x
2. Subtract 4x from both sides:
7x - 4x - 9 = 24 + 4x - 4x
3x - 9 = 24
3. Add 9 to both sides:
3x - 9 + 9 = 24 + 9
3x = 33
4. Divide both sides by 3:
3x ÷ 3 = 33 ÷ 3
x = 11
5. Check your work:
7x - 9 = 28 + 4(x - 1) [substitute 11 for x]
7(11) - 9 = 28 + 4(11 - 1) [simplify]
77 - 9 = 28 + 4(10) [simplify]
68 = 28 + 40 [add]
68 = 68 ✔

Answer:
-1
Step-by-step explanation:
Square root 1 is 1. Add that to the 12 to get 13. Subtract 13 from both sides to get: -5x = 5. Divide both sides by -5 to get your answer: -1
3(2)+2(3)=12 <<<< is the answer! :)
