16 z3 + ( - 21 z3 ) :
Remove parentheses :
= 3 * 16 z - 3 * 21 z
= 48 z - 63 z
= - 15 z
hope this helps!.
Answer:
See below
Step-by-step explanation:
Need the choices.....
essentially, you can multiply this equation by any constant to get an equivalent equation with the same solutions.
x^2 + 8x + 2 = 0 multiply both sides by '3' to get
3x^2 + 24 x + 6 = 0 <===== this will have the same solutions
or this one:
x^2 + 8x + 2 = 0 Multiply both sides by '6' to get
6x^2 + 48x + 12 = 0 <===== this will have the same solutions also
etc....

Step-by-Step

A dilation is a transformation, with center O and a scale factor of k
that is not zero, that maps O to itself and any other point P to P'.
The center O is a fixed point, P' is the image of P, points O, P and P'
are on the same line.
Thus, a dilation with centre O and a scale factor of k maps the original figure to the image in such a way that the<span>
distances from O to the vertices of the image are k times the distances
from O to the original figure. Also the size of the image are k times the
size of the original figure.
In the dilation of triangle TUV</span>, It is obvious that the image <span>T'U'V' is smaller than the original triangle TUV and hence the scale factor is less than 1.
</span>The ratio of the
distances from A to the vertices of the image T'U'V' to the distances
from A to the original triangle TUV is the scale factor.
The scale factor = 3.2 / 4.8 = 2/3
If the perimeter of equilateral triangle is 77 and the equation showing the perimeter is 6.5X-1 then the value of X is equal to 12.
Given that the perimeter of equilateral triangle is 77 and the expression showing the perimeter is 6.5X-1.
We are required to find the value of X which is used in the expression.
Expression is combination of numbers, fraction, coefficients, indeterminants, determinants, which are mostly not found in equal to form.
Perimeter which is given is 77 and 6.5X-1.
6.5X-1=77
6.5X=77+1
6.5X=78
X=78/6.5
X=12
Hence if the perimeter of equilateral triangle is 77 and the expression showing the perimeter is 6.5X-1 then the value of X is equal to 12.
