Hello!
You can expand the 4
4x + 8
the answer is 4x + 8
Hope this helps!

❖ Mean = 4.8 Median = 4.5
The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.8
To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:
4 + 5 = 9
9 ÷ 2 = 4.5

You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16
x = 0.64
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>
Because there are two variables and only one equation, we cannot solve for the exact value of y.
However, we can still get a value of y.
y - 4 = 3x + 5y
Subtract y from both sides.
-4 = 3x + 4y
Subtract 3x from both sides.
-4 - 3x = 4y
Divide all terms by 4.
(-4 - 3x)/4 = y
Answer:
x must be 5
Step-by-step explanation:
Recall that the area formula for a trapezoid is
A = (average of base lengths)(width)
Here we have
17 cm + x
(average of base lengths) = 11 cm = ----------------
2
So 2(11 cm) = 17 cm + x, or
22 cm = 17 cm + x
Then x must be 5.
