Answer: Hello this is my first time answering!
DA= 4.5
CB=4.5
XY=9
If YZ=8 then CD=4
Perimeter of trapezoid ABCD=19
Perimeter of trapezoid WXYZ=38
Step-by-step explanation:
I am almost positive the scale is 0.5/1 this means that for DA it would be 4.5. Of course, if DA was 4.5 then so would CB. Everything is half of the second trapezoid.
Thanks!
The diagonal of length 2r forms the hypotenuse of a right angled triangle with one leg ( the width of the rectangle) = x. So by Pythagoras:-
(2r)^2 = h^2 + x^2 where h = height of the rectangle
h^2 = 4r^2 - x^2
h = √ (4r^2 - x^2) answer
Answer:
-16
Step-by-step explanation:
So you want to change the - into a + and the negative sign before the 13 also into a plus. So it is -29 + 13 and that would be -16 ^.^ Hope this helped!!
Answer:
Let the number of nickels be x
Let the number of pennies be y
Let the number of dimes be z
Now z=x+y
FIrst equation:
z+x+y=16
Subsittue for z:
x+y+x+y=16
y=8-x (subsitution)
Hope this helps :)
