Given that:

a=2, b=-2

Substituting these values,

2a^{2} b+2ab^{2} +ab

=  > 2 \times ({2} \times 2) \times ( - 2) + 2 \times 2 \times ( - 2 \times  - 2) + (2 \times  - 2)

=  > 2 \times 4 \times ( - 2) + 4 \times 4 + ( - 4)

=  > 8 \times ( - 2) + 16 + ( - 4)

=  >  - 16 + 16 +  (- 4)

As first two 16's will be cancelled as they have opposite signs, so, the remaining is,

- 4

(SAT Prep) How many distinct triangles are for which the lengths of the sides are 5,9 and n, where n is an integer and 10
Nana76 [90]
The answer is C because you can have a triangle with 5,9,n   5,10,n   9,10,n   and 5,10,9

The reason why is because the sum of two sides is always larger than the value of the third side.

I hope that this helps.

Answer:

x = 2.5 inches. Or

x = 5/2

Step-by-step explanation:

Length: 7 + 2x

Width: 5 + 2x

Note that you have to add x at each end of the picture and onto each part of the width.

The entire area is 120 square inches.

Formula

L*W = Area

(2x + 7)(2x + 5) = 120

Solution

4x^2 + 10x + 14x + 35 = 120                Subtract 120 from both sides. Add xs

4x^2 + 24x + 35 - 120 = 0

4x^2 + 24x - 85 = 0                             Factor

(2x + 17)(2x - 5)

2x + 17 has no meaning. It will give -  8.5 which is not possible.

2x - 5 =0

2x = 5                                                  Divide by 2

x = 5/2

x = 2.5

Note: I don't know which one the computer is looking for.
