Answer:

Pretty sure it's ab + ab

Step-by-step explanation:

Taking the test myself.. if it needs to be even for all integers and it doesn't give us numbers for a or b then ab + ab is the only "even for all integers"

10) Solve using any method<br> 10x+2y=42<br> 5x+y=20
KIM [24]

Answer:

no solutions

Step-by-step explanation:

10x+2y=42

5x+y=20

Multiply the second equation by -2 to use elimination

-2(5x+y)=20*-2

-10x -2y = -40

Add this to the first equation

10x+2y=42

-10x -2y = -40

--------------------------

0 = 2

This is never true.  This means there are no solutions

The oven tray is 600mm by 500mm. A cake tin is 25cm in diameter. How many cake tins can jenny fit on the oven tray at one time?
vlada-n [284]
Area of Circle= \pi &#10;r^{2}
                      = \frac{22}{7} x ( \frac{25cm}{2}) ^{2}
                      = 490.87cm^{2}

Area of Oven tray= 60cm x 50cm
                            = 3000cm^{2}

: . # tin that can hold on bake tray= 3000cm^{2} / <span>490.87cm^{2}                                 = 6.11
Thus making it logically 6..... </span>

Coefficient of b in expansion of (3+b)^4
Margarita [4]
Are you sure you want ONLY the coefficient of b?  If you expand this, you will have b in 3 of 4 terms.

According to Pascal's Triangle, the coefficients of (a+b)^4 are as follows:

                             1
                        1    2    1
                   1      3    3     1
              1       4     6     4     1

So (a+b)^4 would be 1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4

Here, you want (3 + b)^4.  Here's what that looks like:

3^4 + 4[3^3*b] + 6[3^2*b^2] + 4[3*b^3] + 1[b^4]

Which coeff did you want?
