Answer:
The slope of the line y = 1 is zero.
Answer:
a = 14
Step-by-step explanation:
Given
9 + a = 23 ( subtract 9 from both sides )
a = 14
Answer: A
Step-by-step explanation:
C lies below g(x) and f(x), so we need 
and 
.
Answer:
c=13 and a=20
Step-by-step explanation:
Here you need to use the Pythagoras theorem :
c²=a² + b²
c = √a² + b²
c = √(12)²+(5)²
c= √144+25
c = √169
c = 13
2) c²=a²+b²
b= √c²-b²
b= √(29)²-(21)²
b = √400
b = 20
In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation
Answer:
13x^2+2x+5
Step-by-step explanation:
that is the right answer
You have to combine the like terms.
