For each parallelogram below, find the value of x.
Will give brainliest for full answer
Answer:
x = 3 and x = 8
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
WA = DR , substitute values
12x - 9 = 5x + 12 ( subtract 5x from both sides )
7x - 9 = 12 ( add 9 to both sides )
7x = 21 ( divide both sides by 7 )
x = 3
------------------------------------------------------
The diagonals of a parallelogram bisect each other, then
QS = [tex]\frac{1}{2}[/tex] QT , that is
8x - 14 = [tex]\frac{1}{2}[/tex] × 100 = 50 ( add 14 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Answer:
x = 3 and x = 8

A number between 10 and 20 is both a foctor of 60 and
a multiple of 6.
What is the number?
Answer:
12
Step-by-step explanation:
List out factors of 60 =
1 x 60 = 60
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 are factors of 60.
List out multiples of 6 from 10 to 20.
12 and 18.
Since 12 is seen on one of the factors of 60 and a multiple of 6 between 10 and 20, the answer is 12.

Why is it a problem to find the square root of a negative number, for example √-4?
Answer:
It is not possible because no number times itself can equal a negative number.
Answer:
Taking the square root of a negative number is a problem because this technically does not follow the rules of a square root. A square root is made of a number times itself, and therefore, is impossible to have a negative times a positive to make a negative total (An example would be √4, as the answer can be 2 (because 2 x 2 = 4) or -2 (because -2 x -2 = 4)).
This means that in order to solve √-4, you must use imaginary numbers. This is represented by "i."
For the example of √-4, your answer would be 2i. These imaginary numbers are used whenever you are square rooting a negative number in order to show that it is breaking the real rules of roots.

a trapezoidal prism has a volume of 1260 cm^3. the height of the prism is 18 cm while the bases of the trapezoid are 12 cm and 8cm. Sketch the prism and find the height of the trapezoidal base
Answer:
7 cmStep-by-step explanation:
Volume of the prism is the product of its base area and height
V = AHV = 1260 cm³H = 18 cmFind base area:
A = 1260/18 = 70 cm²Area of the trapezoid:
A = 1/2(b₁ + b₂)hSubstitute given values and solve for h:
70 = 1/2(12 + 8)h70 = 10hh = 70/10h = 7 cmFind area of base

anyone tell me the answer
Answer:
a. Pop
b. 30 CDs
c. 230 CDs
Step-by-step explanation:
Given that "O" represents 20 CDs
a. The CD that was the mode is the CD that has as much "O", which is Pop.
Mode = Pop
b. Number of Rock CDs = 3 × 20 = 60 CDs
Number of Classical CDs = 1½ × 20 = 30 CDs
Therefore, 30 more CDs of Rock were sold than Classical CDs were sold
c. Pop = 5*20 = 100 CDs
Jazz = 2*20 = 40 CDs
Classical = 1½*20 = 30 CDs
Rock = 3*20 = 60 CDs
Total sold altogether = 100 + 40 + 30 + 60
= 230 CDs

Cosx=4/5 what is sin2x cos2x and tan2x
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5
