Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.
It’s A. $25.20
You find the rate you dividing the cost ($18) by how many gallons (5). Then you multiply by what you are looking for (7 gallons). You get 25.20.
So the first four terms of the sequence are
2, 6, 10, 14
Answer:
f(9) = 35
Step-by-step explanation:
To solve this, you can take 9 and replace both x's with it and then complete the equation;
f(x) = 4x - 1
f(9) = 4(9) - 1
f(9) = 36 - 1
f(9) = 35
Hope this helps!
