Answer:
=
Step-by-step explanation:
Steve set the equation equal to 50 which is the entire length of JL. instead he should've set the equation equal to 25, since it's half of 50 and would represent the midpoint. he should've said 2x + 5 = 25
Answer:
- 0.5 - 1.7 = - 2.2
Step-by-step explanation:
We need to add two numbers using the number line.
Steps to Add Numbers on the Number Line:
When we add a negative numbers that we move the point to the left of the number line.
We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.
So, we get 2.2 on the left.
2.2 is left side it means sign is negative.
Final answer is -2.2
Answer:
REALS. all real numbers are solution for the equation
Step-by-step explanation:
for the equation
x² = (x + 3)*(x − 3) + 9
distributing the terms in the parenthesis
x² = (x + 3)*(x − 3) + 9 = [x² - 3*x + 3*x - 3*3 ] + 9
x² = x² - 9 + 9
0 = 0
since this statement will be true regardless of the value of x , then the equation has solution for all real numbers .
Step-by-step explanation:
A=140sq. units
