The area of rectangular is 64m the length of the pool is 12 m less that the width .The situation can be represented by the equat
beks73 [17]

Answer:

Width = 16 m

Length = 4 m

Step-by-step explanation:

The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x

Area of a rectangle = Length × Width

L = W - 12

Hence:

64 = (W - 12) × W

64 = W² - 12W

W² - 12W - 64 = 0

Factor using

(W + 4)(W - 16) = 0

Width = 16m

Length = W - 12

Length = 16 m - 12 m

= 4 m

Divide using long division. Checky<br> (x3+ 3x2 + x - 9) = (x - 1)
Montano1993 [528]

Answer:

x squared plus 2x minus 1.

Step-by-step explanation:

x3+3x2+x-9 is in the division "house" and x-1 is on the outside. xsquare times x equals x cubed. and x square times negative 1 equals -x squsre. put x square on top of the roof. change the signs. the x cubed cancels out. and bring down 2x square from subtracting 3x square and -x square and bring down the x-9. Put 2x on top of the roof too and 2x times x equals 2x square and multiply by -1. U will have 2x square -2x square and -2x plus x which equals -1x cuz the 2x square cancels out. bring down the -9. Now i have -1x-9. Multiply by -1 and put -1 on the roof. -1x+1x cancels out. and -1 times -1 equals positive 1. So -9+1=8. U van do any further cause as soon as the last number is at the end of the roof and u cant go further, ur done dividing. so the answer is x square+2x-1/×-1 +8 as the remainder. hope i helped

Solve the formula for the indicated variable. k=g-d/c for g
Murrr4er [49]
Just like any other variable, we complete the same process

k = g -  \frac{d}{c}  \\ k  +  \frac{d}{c}  = g \\  \frac{kc + d}{c} = g \\
Now we can test it, let's say k=4, d=6, and c=2, let's find the value of g
4 = g -  \frac{6}{2} \\ 4  +  3 = g \\ 7= g

OR

\frac{kc + d}{c} = g \\   \\  \frac{(4 \times 2) + (6)}{(2)} = g \\  \frac{14}{2}  = g \\ g = 7
