Answer:
You can use Pythagoras theorem to calculate x:
12² + 14² = x²
144 + 196 = x²
x² = 340
x = √340 ≈ 18,44
Answer:
Perpendicular lines are lines that intersect at a right (90 degrees) angle
Step-by-step explanation:
2y -3 >-1
2y > 2
y > 1
OR
1 > Y
Y < 1
Since it is only one, D is the correct answer
Answer:
y=7
Step-by-step explanation:
-6y= -27-15
-6y= -42
y=7
Answer:
The answer is 33.
Step-by-step explanation:
4x^2 + 13 - 2y, x=3 y=8
In order to evaluate this, you just need to plug the x and y in the expression:
= 4(3)^2 + 13 - 2(8)
= 4(9) + 13 - 16
= 36 + 13 - 16
= 33
