Answer:
<u>Variables</u> are used to represent an unknown quantity in a mathematical expression.
Step-by-step explanation:
- Variables are used to represent an unknown quantity in a mathematical expression.
- For example : x + 2 = 4, here x is the variable.
- We can denote variable by any alphabet i.e, a,b,c,d etc.
Answer:
60°
Step-by-step explanation:
All the sides are of equal length, 12,12,12 , 60,60, ?, so it is 60
Answer:
Simplify both sides of the equation to get a^2 + 2ab + b^2 - c^2 = 2ab. Then subtract 2ab and add c^2 to both sides of the equation
Step-by-step explanation:
(a+b)^2 - c^2 = 4(1/2 ab)
Simplify both sides
a^2 + 2ab + b^2 - c^2 = 2ab
Subtract 2ab and add c^2 to both sides
a^2 + 2ab + b^2 - c^2 - 2ab + c^2 = 2ab - 2ab + c^2
a^2 + b^2 = c^2
Answer is the second option
Simplify both sides of the equation to get a^2 + 2ab + b^2 - c^2 = 2ab. Then subtract 2ab and add c^2 to both sides of the equation
Answer:
second choice!
Step-by-step explanation:
2x-1 > x+2
[subtract x from both sides]
x-1 > 2
[add 1 to each side]
x > 3
- - - - -
our answer, to fit the inequality, should be:
- dot on the positive 3
- open dot on the line
- the right side of the dot should be highlighted
now choose the second graph since it fits all the requirements!
if i'm wrong pls let me know and always double check bc sometimes im dumb yeah <//3
