Answer:

option a) 30 : 19

Step-by-step explanation:

$Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}$

<em><u>Ratio of length to width:</u></em>

$\frac{15}{2} : \frac{19}{4}$ <em><u></u></em>

$=\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19$

Answer:

D

Step-by-step explanation:

We want to find:

$(x^2+2x-3)(4x^2-5x+6)$

Distribute:

$=(x^2+2x-3)(4x^2)+(x^2+2x-3)(-5x)+(x^2+2x-3)(6)$

Distribute:

$=(4x^4+8x^3-12x^2)+(-5x^3-10x^2+15x)+(6x^2+12x-18)$

Rearrange:

$=(4x^4)+(8x^3-5x^3)+(-12x^2-10x^2+6x^2)+(15x+12x)+(-18)$

Combine like terms:

$=4x^4+3x^3-16x^2+27x-18$

The answer is D.

What is the area of the figure drawn on the coordinate plane below?

Alex17521 [72]

Answer:

C

Step-by-step explanation:

You can just count the number of squares (which I did)

Or you can divide the composite shape into multiple rectangles, find their side lengths, and use the rectangle area formula to find the areas of each of the rectangles and add them all up together.

Find the volume <br> SHOW WORK

vesna_86 [32]

Answer:

The volume is 1120 units³.

Step-by-step explanation:

The volume of a prism is the multiplication of the cross sectional area by its length.

Therefore, find the area of the triangle, and then multiply it by the length:

$v = ( \frac{8 \times 14}{2} )(20) = \\ = (4 \times 14)(20) = \\ = 56(20) = \\ = 1120$
