How do you write 2x^3 + 2x^2 - 3 as a trinomial?

Answer:

True

Step-by-step explanation:

[tex]-2a>6[/tex]

Multiply both sides by -1 (Flip the signs and symbol):

[tex]\left(-2a\right)\left(-1\right)<6\left(-1\right)[/tex]

[tex]2a<-6[/tex]

Divide both sides by 2:

[tex]\frac{2a}{2}<\frac{-6}{2}[/tex]

[tex]a<-3[/tex]

Step-by-step explanation:

7a

x2 + 4x + ax + 4a

x2 + ax + 4x + 4a

x (x + a) + 4 (x + a)

:(x + 4)(x+a)

7d

x2+2x-ax-2a

x2-ax+2x-2a

x (x-a)+2 (x-a)

:(x+2)(x-a)

7h

x2-2bx-5x+10b

x2-5x-2bx+10b

x (x-5)-2b(x-5)

:(x-2b)(x-5)

Answer:

You have to take out the common terms :

Question A,

[tex] {x}^{2} + 4x + ax + 4a[/tex]

[tex] = x(x + 4) + a(x + 4)[/tex]

[tex] = (x + a)(x + 4)[/tex]

Question D,

[tex] {x}^{2} + 2x - ax - 2a[/tex]

[tex] = x(x + 2) - a(x + 2)[/tex]

[tex] = (x - a)(x + 2)[/tex]

Question H,

[tex] {x}^{2} - 2bx - 5x + 10b[/tex]

[tex] = x(x - 2b) - 5(x - 2b)[/tex]

[tex] = (x - 5)(x - 2b)[/tex]

Answer: 6 x X > 20

so we know its greater than 3 because  X>3 x 6 is 18, so I assume 4 which makes 24 if multipled by 6

Answer:

8

Hope this helps!

The discriminant of the given quadratic equation is 8.

The discriminant determines the type and number of solutions that the equation has.

If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one repeated real solution. If the discriminant is negative, the equation has no real solutions.

Given is a quadratic equation -x²+4x-2 = 0, we need to find the discriminant of the quadratic equation,

So,

D = b²-4ac

Here,

a = -1, b = 4 and c = -2

Therefore,

D = 4² - 4(-1)(-2)

D = 16 - 8

D = 8

Hence, the discriminant of the given quadratic equation is 8.

Answer:

b=3

Step-by-step explanation:

Use PEMDAS

It says Parentheses first.

4*b, 4*(-2)= 4b, -8

2*5, 2*-b= 10, -2b.

Write the equation out:

4b-8=10-2b

Add 8 to both sides

4b=18-2b

Add 2b on both sides

6b=18

Divide both sides by 6

b=3

Answer: 868 miles

Step-by-step explanation:

Given: The scale from a map to actual distance is 2.5 cm to 620 miles.

i.e. 1 cm on map  = [tex]\dfrac{620}{2.5}\text{ miles}=248 \text{ miles}[/tex]

If the distance on the map between Chicago and Boston is about 3.5 cm.

Then, the actual distance between them =  [tex]3.5\times 248 \text{ miles}=868 \text{ miles}[/tex]

Hence, the approximate distance between Chicago and Boston = 868 miles.
