Answer:
16
Step-by-step explanation:
The first thing you would do is the 1+3, because parentheses are solved first. This gives you 4 and subsequently 8/2 * 4.
Next you would do 8/2. Multiplication and divison have the same priority so this is done left to right: 8/2 =4, giving us 4 * 4.
Four times four is sixteen.
3x² + 14x + 8
3x² + 12x + 2x + 8
3x(x) + 3x(4) + 2(x) + 2(4)
3x(x + 4) + 2(x + 4)
(3x + 2)(x + 4)
Answer:
10 ??
Step-by-step explanation:
First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
