Answer:
<h2>
Marianna is incorrect because x2</h2><h2>
2x13 can be factored into two binomials</h2>
Step-by-step explanation:
ax^2+bx+c = 0
x=−1+√14 or x=−1−√14
discriminant=56
completing square x=−1+√14 or x=−1−√14
Now, we can solve each term for
x=-2 she is incorrect
x(x+2)=0
Now, we can solve each term for
0:
x=0
- no other work needed,
and
x+2=0
x+2-2=0-2
x+0=-2
<u>x=-2</u>

First, we need to take the square root of each side.
Second, we now have to find the square root of 169 to solve this. Since 13 × 13 = 169, the square root of 169 is 13. The plus-minus symbol means in this case, the solution can be -13 and positive 13. To answer your question, option A) 13, and B) -13 are the solutions to the equation.
Answer:
Answer:
B) −3(x − 1.7)
Step-by-step explanation:
Apply the distributive property of multiplication over addition or over subtraction in each case, which is a(b + c) = ab + ac or a(b - c) = ab - ac.
A) −3(x + 1.7) = = -3(x) + (-3)(1.7) = -3x - 5.1
B) −3(x − 1.7) = -3(x) - (-3)(1.7) = -3x + 5.1 <------------ answer
C) 3(x + 1.7) = 3(x) + 3(1.7) = 3x + 5.1
D) 3(x − 1.7) = 3(x) - 3(1.7) = 3x - 5.1
