5 0

Answer:

20

Step-by-step explanation:

You are trying to find the value. To do so, simply simplify the expression. Combine the terms:

20 + 8 - 4 - 4

(20 + 8) + (-4 - 4)

28 + (-8) = 28 - 8 = 20

20 is your answer.

Ray CE is the angle bisector of ACD. Which statement about the figure must be true?
Viefleur [7K]

we know that

"Bisect" means to divide into two equal parts

so

If the ray CE is the angle bisector of ADC

then

Angle(ACD)=Angle(ACE)+Angle(ECD)

Angle(ACE)=Angle(ECD)

so

Angle(ACD)=2Angle(ACE)

Angle(ACE)=\frac{1}{2} Angle(ACD)

therefore

<u>the answer is the option</u>

Angle(ACE)=\frac{1}{2} Angle(ACD)

or

Angle(ACE)=Angle(ECD)

Which ordered pair is a solution of the equation? -x-4y=-10
Makovka662 [10]

Answer:

(2, 2 )

Step-by-step explanation:

To find a solution, choose any value for x, substitute into the equation and solve for y.

Choose x = 2, then

- 2 - 4y = - 10 ( add 2 to both sides )

- 4y = - 8 ( divide both sides by - 4 )

y = 2

Thus (2, 2 ) is a solution to the equation

Use the diagram to determine which statement is true
hichkok12 [17]
A. Area of ABCD - Area of DGA = Area of DEFG
s^2 - 1/2bh = s^2
(5)^2 - 1/2(4)(3) = (3)^2
25 - 1/2(12) = 9
25 - 24 = 9
1 not equal to 9

B. Area of ABCD - Area of GHIA = Area of DGA
s^2 - s^2 = 1/2bh
(5)^2 - (4)^2 = 1/2(4)(3)
25 - 16 = 1/2(12)
9 not equal to 6

C. Area of ABCD + Area of DGA = Area of GHIA
s^2 + 1/2bh = s^2
(5)^2 + 1/2(4)(3) = (4)^2
25 + 1/2(12) = 16
25 + 6 = 16
31 not equal to 16

D. Area of DEFG + Area of GHIA = Area of ABCD
s^2 + s^2 = s^2
(3)^2 + (4)^2 = (5)^2
9 + 16 = 25
25 = 25

The answer is D.
