Answer:
x= -1 (looks like C)
Step-by-step explanation:
To solve for x, factor the quadratic. Begin by factoring out a GCF of 5.
To factor the remaining parts of the quadratic, look for two factors of 5 which add to 6. This would be 1 and 5.
So the quadratic factored is:
To solve for x, set each factor equal to 0 and solve.
x+1 = 0
x = -1
x+5 = 0
x=-5
-1 is the largest solution.
Answer:
The scale factor used is 0.4
Step-by-step explanation:
Given
Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;
In this case; R' is the new length and R is the old length
Substitute the values of R and R'
Factorize the denominator
<em>Hence, the scale factor used is 0.4</em>
