Which equations are true for x = –2 and x = 2? Select two options

Mathematics

The equations that are true for x = -2 and x = 2 are x^{2} -4 = 0 and 4x^{2} = 16

<h3>What is an equation?</h3>

An equation is a mathematical statement that establishes the equality of two quantities.

Analysis:

Testing the equation x2 - 4 = 0

for x = 2,  (2)^{2} - 4 = 4-4 = 0

for x = -2 = (-2)2 - 4 = 4-4 = 0

Therefore x2-4 = 0 is true

Testing for 4x2 =16

for x  = 2 , 4(2) ^2 = 4x4 = 16

for x = -2 4(-2)^2 = 4(4) = 16.

All other equations are not true except these two.

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.
