Answer:
Option d
Step-by-step explanation:
given that a, b, c, and d be non-zero real numbers.

we can factorise this equation by grouping

Equate each factor to 0 to get

Ratio of one solution to another would be

So ratio would be ad/bc
Out of the four options given, option d is equal to this
So option d is right

Step-by-step explanation:
Answer:
The parametric hypothesis tests that we introduced in Chapter 5 were all based upon the means of the sample and population.
The value of x is
1. x= -37/48
2. x=0
3. x = 33/4
4. x= -20/7
<h3>What is equation?</h3>
A mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
1. 6(8 x + 6) + = - 1
48x + 36 = -1
x= -37/48
2. 9x/7 + 6 = 6
9x/7= 6-6
9x/7 =0
x= 0*7/9
x= 0
3. 2x/11 (11 - 7) = 6
x * 4= 6*11/2
4x= 33
x = 33/4
4. 11x/4 (4 - 2) = 9x + 10
11x/4 * 2 = 9x +10
11/2*x = 9x +10
-7/2x = 10
x= -20/7
