Factor the following Polynomials 2x2 + 5x + 2

Mathematics
1 answer:
Leokris [45]2 years ago
3 0

Answer:

Step-by-step explanation:

Find the multiples of 2x^2 and 2

for 2x^ you get 2,1 but they need to have x  to get x^2 so; (2x and x)=2x^2

for 2 you get 2,1 (2x1)=2

Because your equation has a 5x and no negatives you know that your factors need to be positive.

(2x+1)(x+2)

when you multiply these you get

2x^2+4x+x+2 (remember 2x multiplies with everything inside (x+2) = 2x^2+4) and so on for the x (x+2) =x+2 )

Then you combine like terms 4x+x=5x

and those are the only like terms available and you get

2x^2+5x+2

Hope it helped

triangle on right is the same as the triangle on the left

use pythagorean theorem

hypotenuse will give to the sides of the rectangle

a^2 + b^2 = hypotenuse squared

10.4^2 = 108.16

15.3^2 = 234.09

342.25 = hypotenuse squared

take the square root in both sides

hypotenuse = the square root of 342.25 =

18.5

add up the areas of the 2 triangles and rectangle

triangle area is 1/2 times 10.4 times 15.3 =

79.56

2 triangles areas are 159.12

rectangle area is 18.5 × 7 = 129.5

159.12 + 129.5 = 288.62

answer 1 = 288.62

second question:

to get 1 side take the

square root of 702.25 which is

26.5

to get the perimeter

multiply 26.5 by 4 which is

106

answer 2 is choice B 106

liberstina [14]

Answer:

x > -2

Step-by-step explanation:

Solve the inequality -4x < 8 using inverse operations. If you divide or multiply by a negative, flip the inequality sign.

-4x < 8\\\\\frac{-4x}{-4} < \frac{8}{-4}

x > -2
