Answer:
b + r = 10 - - (1)
2r + 3b = 23 - - (2)
Step-by-step explanation:
Number of Blue pens in box A = b
Number of red pens in box A = r
BOX A :
Contains 10 pens that are either red or blue
b + r = 10
BOX B:
Contains 23 pens that are either red or blue ;
Red pens in box B = 2 tines the number of red pens in box A
Blue pens in box B = 3 times the number of blue pens in box A
2r + 3b = 23
⓵ The pythagorean theorem is calculated by using this formula : a² + b² = c²
“a” is the length of one of the legs
“b” is the length of the other leg
“c” is the length of the hypotenuse
⓶ Now that you have the formula, replace the letters in the formula with the information that you have :
8² + b² = 10²
⓷ Now that this is done, you need to isolate the “b²” in order to find the length of the other leg of the triangle :
8² + b² = 10²
-8² -8²
↓
b² = 36
√b² √36
↓
b = 6
So the final answer is : the length of the other leg of the triangle is ↠ 6 feet
I really hope this helped, if there’s anything just let me know! ☻
Answer:
a=2, b=2, c=-12
Step-by-step explanation:
Since it's in factor form, you would first distribute using foil to get 
and then combine like terms when necessary. In this case, the fully simplified version is 
. Therefore your a is 2, b is 2, and c is -12.
