Answer: B. No

Step-by-step explanation: Let's think of the variable x as apples. If there are 7 apples and then you added 1 other something, that would be different than having 1 apple and adding 7 other somethings. The equations would have a different amount of somethings and apples.

decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring. −b b2 − 4ac 2a u
Romashka [77]

Answer:

Step-by-step explanation:

A quadratic equation can be factorised if and only if there are rational roots.

For any quadratic equation the discriminant decides about the nature of roots.

Thus only if the discriminant is a perfect square we can have rational roots and in this case only factorization is possible.

In the given equation

2x^2+ 7x+ 3 = 0\\a=2, b=7, c=3\\b^2-4ac = 1

Since 1 is a perfect square we can factor and solve

2x^2 +7x +3 = 0\\(2x+1)(x+3)=0\\x=-1/2 or x = -3

A rectangle has an area of 1/6 square centimeters and a length of 1.5 centimeters. what is the width? what is the perimeter?
SCORPION-xisa [38]
The area of a rectangle can be calculated by the product of its length and the width. Here we are given the area and the length so we can simply calculate for width. The perimeter is the sum of all the side lengths of the shape. We calculate as follows:

Area = lxw
1/6 = 1.5w
w = 1/9

Perimeter = 2l + 2w
Perimeter = 5/9

Hope this answers the question. Have a nice day.
