Answer:
Option A. k = 4.5, 54 cm
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem the constant of proportionality is equal to the scale factor
step 1
Find the scale factor
Let
k -----> the constant of proportionality
-----> ratio of the corresponding sides
step 2
Find the value of x

therefore
k = 4.5, 54 cm
Answer:
Y=2x - 3/4
Step-by-step explanation:
The slope is calculated by y-y over x-x. That equals 2. The. You put the x and y coordinates in to get the y intercept which is -3/4
Answer: the answer is c
Step-by-step explanation: I just know that
The expression 2x⁴ + 5x³ - 8x - 20 can be express as follows;
x³(2x + 5) - 4(2x + 5)
<h3>How to factorise an expression?</h3>
2x⁴ + 5x³ - 8x - 20
Therefore,
2x⁴ + 5x³ - 8x - 20
x³(2x + 5) - 4(2x + 5)
Hence, the expression 2x⁴ + 5x³ - 8x - 20 can be express as follows:
2x⁴ + 5x³ - 8x - 20 = x³(2x + 5) - 4(2x + 5)

X=1/2 I’m mostly guessing but for math just use the app called photo math it’s helps with math equations but not math written problems
