Factor completely: 2x^2 + 2x − 24. Thank you

2x^2 + 2x - 24 Factor out a 2 2( x^2 + x - 12) Now we can factor our equation into... 2 (x - 3)(x + 4) If you need the zeroes.. x - 3 = 0 x = 3 x + 4 = 0 x = -4 x = -4, 3

Based on the graph of the following system of equations, determine the number of solutions.

2x + 3y = 9 6y = 5 − 4x A. No solutions B. Exactly one solution C. Exactly two solutions D. Infinitely many solutions-Write these asy=-(2/3)x+3y=-(4/6)x+5=-(2/3)x+5. These are straight lines with t

What is 12/13 + 7/8? I don't know

The answer is either: 1 2 19 21-Im guessing youre supposed to round it, so 2. You solve it by first finding a common denominator for both fractions. In this case it is 104. 8 x 13 = 104 So it wou

If a=7 and b=28, what's ( a + b ) to the power 2

plz help-Add a and b then multiply by its self 35 x 35 = 1225, thats the power of 2, power of 3 is 35 x 35 x 35...etc..etc..-(7+28)^2 (35)^2 1225-all you need to do is replace the a and b with your va

Find the x-and y- intercept-4x-5y=30 -4x-5y=30-4x-5y=30 -4(0)-5y=30-4x-5(0)=30 0-5y=30-4x-0=30 5y=30-4x=30 y=6x=-7.5 or- 8 (0,6)(-7.5 or -8, 0)-y-intercept means when x = 0 as follows: -4x - 5y = 30

What is the exact value of the expression √32 + √75 - √98? Simplify completely.

First find 2 products of the numbers and one has to be a perfect square. √32 = √ 16 x 2 which is simplified to 4√ 2 √ 75 = √ 25 x 3 = 5 √3 √98 = √49 x 2 = 7√ 2 4√2 + 5√3 - 7√2 This is simplified t
