Factor 2x2 + 7x + 3.

Mathematics
1 answer:
Makovka662 [10]3 years ago
7 0

Answer:

( 2x + 1 ) (x + 1 )

Step-by-step explanation:

2x² + 7x + 3

m+n = b = <u>7</u>

m · n = a · c = 2 · 3 = <u>6</u>

m = 6

n =  1 because 6 + 1 = <u>7</u> and 6 · 1 = <u>6</u>

2x² + <u>1</u>x + <u>6</u>x + 3

x ( 2x + 1 ) + 3 ( x + 1 )

( 2x + 1 ) (x + 1 )

ololo11 [35]
2x-6 (2) is your equation. follow these steps, and you have to distribute 6 into 2 like this: 2x-12. you get negative 12 because -6 x 2 =-12. now you divide -12 by 2 which is -6. So -6=x

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approx
Angelina_Jolie [31]

Answer:

168.168 square inches

Step-by-step explanation:

Given data

From the question, we can deduce that the side of the square is 28in

Hence the area of the square is

Area= 28^2

Area= 784 square inches

Also, the diameter of the circle is 28 in

The radius = 14 in

Area of circle= πr^2

Area= 3.142*14^2

Area= 3.142* 196

Area= 615.832 square inches

Therefore the area of the shaded region is

= Area of Square - Area of Circle

= 784-615.832

=168.168 square inches

A motorcycle can travel 60 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 40 km?
Semenov [28]
The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42

Simplify by combining like terms 5x+3y+3x
Aliun [14]

Answer:

8x+3y

Step-by-step explanation:

1. Find like terms: 5x and 3x share the same constant "x" so you can combine them. There is nothing to combine with the 3y since there is no other term with the constant "y".

2. Rearrange to make it easier to see: 5x+3x+3y

3. Add the 5x and 3x: 8x+3y
