Answer:
-4x^2+5x-28
Step-by-step explanation:
3x^2 +5x - 7(x^2 +4)
Distribute the -7
3x^2+5x-7x^2-28
Combine like terms
-4x^2+5x-28
Step-by-step explanation:
47)25+35x+4x-1=180
24+39x=180
39x=180-24
39x=156
x=4
48)70+9x-5+13x+5=180
70+22x=180

To find median, you must first order the numbers from least to greatest.
$3.85, $4.79, $4.85, $5.38, $5.96
Since there is an odd amount of numbers, the median is the middle number.
In this case, the number in the middle is $4.85.
This means that the median is $4.85.
Hope this helps!
Answer:
a = 3
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 8² = ( )²
a² + 64 = 73 ( subtract 64 from both sides )
a² = 9 ( take the square root of both sides )
a = = 3
