Answer:
T and F
Step-by-step explanation:
Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.
"A square root of 16 is 4."
4 squared, or 4 * 4 is equal to 16, and therefore this is true.
"The only square root of 9 is -3."
This is false. 9 has 2 square roots: 3 and -3.
3 * 3 = 9, and so does (-3) * (-3).
So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.
Hope I helped! :)
Answer:
x=31
Step-by-step explanation:
we need to isolate x so we put 48 t the other side to make -x=17-48
we do 17-48 =-31 so -x=-31
x=31
Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116
Answer:
1. vertical-line test
2.y=x
3.x
4.domain
Step-by-step explanation:
I just did it on edg and it’s right.
All the angles have to equal 180. If you add the two angles you get 140. You take 180 and subtract 140 and it equals to 40. The missing angle is 40 degrees.
