Answer:
The scale factor for the resultant rectangle is
units.
Step-by-step explanation:
Given two rectangles with sides 3 units and 7.5 units.
We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.
Scale factor is defined as the ratio of corresponding side of given figure to the corresponding side of resulting figure.
That is 
Here, 

Hence, the scale factor for the resultant rectangle is
units.
Answer:
20cm or A
Step-by-step explanation:
pythagorean theorem
25^2=15^2+b^2
625=225+b^2
b^2=400
b=20
Your answer is C I’m sure about that!
Answer:
x³-9x²+14x+24
Step-by-step explanation:
here given : 4, -1, 6
so put negative value of each digit in the equation
(x-4)(x+1)(x-6)
(x²-4x+x-4)(x-6)
(x²-3x-4)(x-6)
(x³-3x²-4x-6x²+18x+24)
x³-9x²+14x+24
