Which expression is not equivalent to (x + 4)(x – 3)?

Digiron [165]

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

${x }^{2} - 3x + 4(x - 3)$

2) Expand by distributing terms.

${x}^{2} - 3x + 4x - 12$

3) Collect like terms.

${x}^{2} + ( - 3x + 4x) - 12$

4) Simplify.

${x}^{2} + x - 12$

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Part C How many cubic blocks are needed to fill the fish tank?

nikklg [1K]

Answer:

$2\frac{2}{3}$ cubic blocks

Step-by-step explanation:

The given parameters are:

$Length = \frac{1}{2}yd$

$Width = 16yd$

$Height =\frac{1}{3}yd$

Required

Number of cubic blocks to fill the tank

To do this, we simply calculate the volume of the tank by:

$Volume = Length * Width * Height$

This gives:

$Volume = \frac{1}{2} * 16 * \frac{1}{3}$

$Volume = \frac{16}{6}$

Simplify

$Volume = \frac{8}{3}$

Express as mixed numbers

$Volume = 2\frac{2}{3}yd^3$

Can someone please help me out with the last one ASAP I WILL GIVE OUT BRAINLY

Answers:

x = 7
Area of shaded region = 162 square units

You may need to leave off the "square units" portion.

=============================================

Explanation:

For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.

L = 3x

W = x+5

The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.

P = 2(L+W)

2(L+W) = P

2(3x+x+5) = 66

2(4x+5) = 66

8x+10 = 66

8x = 66-10

8x = 56

x = 56/8

x = 7

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

Now that we know x, we can find the area of the rectangles.

As you probably can guess, the shaded region is the difference of the two areas.

A = area of larger rectangle

A = (length)*(width)

A = (3x)*(x+5)

A = (3*7)*(7+5)

A = 252

B = area of smaller rectangle

B = (x+3)*(x+2)

B = (7+3)*(7+2)

B = 90

C = area of shaded region

C = A - B

C = 252 - 90

C = 162 square units is the area of the shaded region.
