Answer:
24x^9*z^5
Step-by-step explanation:
combine coefficients and add exponents for like terms
hope this helps you :)
X - 2x =6
X= - 6
Let x = −6
−6=2×−6+6
Simplify
2 ×−6 to −12
−6=−12+6
Simplify -12+6 to -6
-6= -6
Answer:
Correct option: D
Step-by-step explanation:
In the figure we have a right triangle, that is, one of the angles is a 90° angle. Therefore, we can use the Pythagoras' theorem to find the relation between the sides of the triangle:
Where b and c are cathetus of the triangle (sides adjacent to the 90° angle) and a is the hypotenuse (opposite side to the 90° angle).
So in our case, we have that x is the hypotenuse, and 40 and 42 are cathetus, so we have:
So the correct option is D.
