Answer: 3x2+5x−4
The 2 behind 3x is an exponent
Answer:
x=5
Step-by-step explanation:
3x+1= 4x+(-4)
-4×+1= -4x-1 combine like terms
-1x= -5 divided by -1
x= 5
4x - 2 = 2x + 8
2x -2 = 8
2x = 10
x = 5
4(5)-2 = 2(5)+8
20-2 = 10+8
18 = 18
Answer:
$6.87
Step-by-step explanation:
For the blueberries we multiply 3.98 with .6 pounds to get 2.39
We do the same for the other item 2.49 X 1.8 = 4.48
Total the two for the answer:
2.39 + 4.48 = 6.87
The formule is about area of a circle.

We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get


Taking square root on both sides, we get
