The value of x is 78 Degrees. The angles are complementary so they are equal.
The equation would be 35=5x. ‘x’ is the number of seashells her brother has, and the 5 in front of the x is showing that she has 5 times more than him. to find how many her brother has, divide both sides of the equation by 5 to make the x stand alone. you should then get 7=x, meaning that her brother has 7 shells
Answer:
Step-by-step explanation:
lets replace x with 3
f(3)= -2(3)^3+3(3+2)=-2*27+15=-54+15=-39
Answer:
C
Step-by-step explanation:
Move the constant to the right by adding it’s opposite to both sides
x+2-2= 7 squared - 2
Next remove the opposites
x= 7 squared -2 is your answer
