<h3><u>Answer:</u></h3>
<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>
<h3><u>Step-by-step explanation:</u></h3><u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>
- => Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
- => Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.
Hoped this helped.
Quadratic equations are second-order equations. Ginney made a mistake when she identified b = 31. It should be b = –31.
<h3>What is a Quadratic Equation?</h3>A quadratic equation is an equation that can be written in the form of
ax²+bx+c.
Where a is the leading coefficient, and
c is the constant.
In order to find the mistake that Ginny made, we will first find the factors ourselves, therefore, we will factorize the trinomial,
As we can see that the value of constants are,
a = 6
b = -31
c = 30
Therefore, the factors of the trinomial are (6x+5) and (x-6).
If we compare our process with Ginny's process, we will find that she has taken the value of the constant b as 31 which is wrong.
Hence, Ginney made a mistake when she identified b = 31. It should be b = –31.
