Answer:
-6
Step-by-step explanation:
1-7(1)=1-7
1-7=-6
You know anything times 1 stays the same there for you just subtract, since it's a positive 1 minus a negative 7 it goes backwards to -6
Answer:
The correct answer is,
3x² - 30 x + 63 = 3(x - 3)(x - 7)
Step-by-step explanation:
The given polynomial is 3x² - 30 x + 63
<u>Factorization of 3x² - 30 x + 63</u>
<u>Splitting method</u>
3x² - 30 x + 63 = 3(x² - 10 x + 21) (taking 3 as common)
= 3(x² - 3 x - 7x + 21) (middle term splitting)
= 3[x (x - 3) -7(x - 3)] (taking x and -7 as common)
= 3[(x - 3)(x - 7)]
Therefore 3x² - 30 x + 63 = 3(x - 3)(x - 7)
The correct answer is 3(x - 3)(x - 7)
Hi there! :)
<u>Infinite solutions.</u>
2x + 8 = 2(x + 4)
Distribute the 2 with the terms inside of the parenthesis:
2x + 8 = 2(x) + 2(4)
Simplify:
2x + 8 = 2x + 8
Subtract 2x from both sides:
2x - 2x + 8 = 2x - 2x + 8
0 + 8 = 8
Subtract 8 from both sides:
0 + 8 - 8 = 8 - 8
0 = 0
Therefore, there are infinite solutions.
Answer:8.385
Step-by-step explanation:
Step 1: multiply both sides by 30 (this sounds crazy, but that's 5 and 6's least common multiple) 1/6(j-1)+4=1/5(3j+1) -> 5(j-1)+120=6(3j+1)
Step 2: Distribute 5(j-1)+120=6(3j+1) -> 5j-5+120=18j+6
Step 3: Combine like terms 5j-5+120=18j+6 -> 5j+115=18j+6
Step 4: Isolate the variable 5j+115=18j+6 -> 109=13j
Step 5: Divide to further isolate 109/13=j= 8.385
