Answer:
C and E
Step-by-step explanation:
We know that
The square root property<span> is one method that is used to find the solutions to a quadratic equation. This method involves taking the square roots of both sides of the equation.
</span>(x – 3)² – 32 = 17-------> (x – 3)² = 17+32-----------> (x – 3)² = 49
(x – 3)² = 7²--------> <span>will take the square root of each side
</span>so
√(x – 3)²=(+-)√7²------> <span>notice the use of the </span> sign (+-), this will give us both a positive and<span> a negative root
</span>
then
x-3=7--------> x=10
x-3=-7-------> x=-4
the answer Part a) is
x=10
x=-4
Part b) Explain why the given equation has two solutions.
the answer part b) is
Because exist<span> the possibility of two roots for every square root, one positive and one negative</span>
Answer:
Volume = 52.5
Step-by-step explanation:
volume of a rectangular 3d shape can be calculated by length*width*height. In this case:
7*10*0.75 = 52.5
Answer:
Chantal and Trisha will have both traveled 105 miles in 20 minutes.
Step-by-step explanation:
is distance in miles, 
is time in hours.
The two equations are:
Set them equal to each other and solve for x:
Plug that back into the equations to confirm this gives the same :
Answer:
2x + 20
Step-by-step explanation:
Hi there,
since there are 2 weeks :
x + x = 2x
10 + 10 = 20
==2x + 20 while simplifying it becomes, 2(x+10)
