Answer:
118
Step-by-step explanation:
Triangle CDE contains angles CDE, DCR and DER
Angles DCR=17 and DER=45 because in a kite, the diagonal on the line of symmetry bisects the angles and 34-2=17 90/2=45
The angles in a triangle add up to 180 and 180-17-45=118, meaning angle DER=118
M= 4/6
<span>4m + 10 = 14 − 2m
6m+10=14
6m=4
m=4/6

7/20 * 2/3 = 14/60 = 7/30
Now, 7/30 / 21/4
= 7/30 * 4/21 = 28/630 = 14/315
In short, Your Answer would be 14/315
Hope this helps!
Answer:
-14x +21 = 7x -24
Step-by-step explanation:
We assume your use of the multiplication symbol in this problem (×) is intended to represent the variable x.
The distributive property tells you that the factor outside parentheses multiplies each of the terms inside parentheses:
a(b+c) = ab+ac
Your equation can be simplified as ...
-7(2x -4) -7 = 3(x -5) +4x -9 . . . . given
-7(2x) +(-7)(-4) -7 = 3x +3(-5) +4x -9 . . . . use the distributive property
-14x +28 -7 = 3x -15 +4x -9 . . . . . . . . . . . carry out the multiplication
-14x +21 = x(3+4) -(15 +9) . . . . identify and group like terms on the right*
-14x +21 = 7x -24 . . . . . . . . . . do the arithmetic
_____
* note that the distributive property can also be used to combine terms:
3x +4x = x(3+4) = 7x
