A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor for volume of one half. The basic equation for it is image over preimage.
In the field of measurements, the scale factor of an instrument is sometimes referred to as sensitivity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor.
We know that the lengths of the two smaller sides have to be more than the third side when they are added together
The third side couldn't be 2 or 3 because 9 (7+2) or 10 (7+3) are not less than 10
The third side couldn't be 17 or 18 because 17 (7+10) is not larger than 17 or 18
The correct answer is C. 4 works because 7+4=11 or more than 10. 16 works because 7+10=17 is more than 16

Answer:
x=2.75
Step-by-step explanation:
4x+5=8x-6
4x-8x=-6-5
-4x=-11
divide -4 by both sides
x=2.75
-19=5(×+9)
-19=5×+45
-19-45=5×
-64=5×
-64/5=×
×=-64/5
Answer:
see explanation
Step-by-step explanation:
given f(x) in factored form, set f(x) = 0 and solve, that is
(x + 16)(2x - 3)(3x + 4) = 0
Equate each factor to zero and solve for x
x + 16 = 0 ⇒ x = - 16
2x - 3 = 0 ⇒ 2x = 3 ⇒ x =
3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = -
The zeroes are
x = - 16, x = , x = -
