Answer:
42 feet
Step-by-step explanation:
You combine the numbers that have the same letter attached to them. Then you add or subtract the bumbers from each other to. After that you make the numbers and the numbers with letters into one equation
Ex: 13+5r+7r= 13+12r
Step-by-step explanation:
2w+w=3w If theres a letter by itself it means theres a 1.
The answer is: [B]: x <span>> -10
__________________________
Explanation:
___________
Given the inequality:
___________
</span>→ <span>x + 2 > - 8 ;
____________
</span>→ Subtract<span> "2" from EACH side; to isolate "x" on one side; and solve, or simplify, for "x" ;
_______________________
</span>→ x + 2 − 2 > - 8 − 2 ; to get:
_______________________
→ x > -10 ; which is: 'Answer choice: [B]'.

Suppose we wish to determine whether or not two given polynomials with complex coefficients have a common root. Given two first-degree polynomials a0 + a1x and b0 + b1x, we seek a single value of x such that
Solving each of these equations for x we get x = -a0/a1 and x = -b0/b1 respectively, so in order for both equations to be satisfied simultaneously we must have a0/a1 = b0/b1, which can also be written as a0b1 - a1b0 = 0. Formally we can regard this system as two linear equations in the two quantities x0 and x1, and write them in matrix form as
Hence a non-trivial solution requires the vanishing of the determinant of the coefficient matrix, which again gives a0b1 - a1b0 = 0.
Now consider two polynomials of degree 2. In this case we seek a single value of x such that
