Answer and explanation:
Given : Equations
1) 
2) 
To find : Tell whether the following equations are true or false. Then, explain your reasoning.
Solution :
Equation means when left hand side and right hand side of the equation is same.
1) 
Take LHS,

Same term with opposite sign cancel each other or sum is zero,


Therefore, Yes, it is true as it satisfy definition of equation.
2) 
Take LHS,

Same term with opposite sign cancel each other or sum is zero,


Therefore, Yes, it is true as it satisfy definition of equation.
Answer:
0
Step-by-step explanation:
3+9=12
12-12=0
Yes you are correct. 602<620. The greater sign goes this way ">". Just think of it as this, the less "<" sign looks like an L. Which stands for less. That's how I think of it.
Answer:
c)11√2
Step-by-step explanation:
Given that two of the angles are equal ,each measuring 45 degrees then two legs will be equal as well each measuring 11 units. We have a right angled triangle with two sides given and we are required to determine the hypotenuse. We use Pythagoras theorem;
hypotenuse^2 = 11^2 + 11^2
hypotenuse ^2 = 242
hypotenuse = 
hypotenuse = 
Supposed that we are given the equation:
7.20 x 10^-5 = x(0.100+x)^2
So assuming that x is very small so that:
0.100 + x ~ 0.100
and calling it x1, so:
7.20 x 10^-5 = x1 (0.100)^2
Then we simply solve for x1:
x1 = 7.20 x 10^-5 / (0.100)^2
<span>x1 = 7.20 x 10^-3</span>
