Answer:

(3x-2)

Step-by-step explanation:

3x² + 4x - 4

look for two factors whose product is (3)(-4)=<em>-12</em> and sum is +4

The factors will be +6 and -2

substitute these factors inplace of 4x to get:

3x² - 2x + 6x - 4

then factorize:

x(3x-2)+2(3x-2)

finally we get factors: (3x-2)(x+2)

Dmitrij [34]

Answer: No, he can't pass the course.

Explanation:

Since we have given that

Marks on tests 1, 2, and 4 are given by

82, 76, 90 respectively.

Unfortunately, he cut the third test and receive a 0.

According to question, we have given that passing grade for the course is 70, and his one test left to take ,

Let the marks obtained in fifth test be x

So,

$\frac{82+76+90+0+x}{5}=70\\\\248+x=5\times 70=350\\\\x=350-248\\\\x=102$

And it is not possible to get 102 over 100.

so, he can't still pass the course.

Hence, No, he can't pass the course.

What is the distance between the two points (5, -2) and (-3, 8)?

galben [10]

Answer:

2√41 ≈ 12.81 units

Step-by-step explanation:

The distance between two points is conveniently found using the distance formula:

d = √((x2 -x2)^2 +(y2 -y1)^2)

d = √((-3-5)^2 +(8-(-2))^2) = √(64 +100) = 2√41 ≈ 12.81 . . . units
