A rectangle has a height of k2 + 3 and a width of k2 + 7.
ElenaW [278]

Answer:

The area of the rectangle in polynomial form is k^4 +10 k^2 + 21

Step-by-step explanation:

Given

Shape: Rectangle

Height: k^2 + 3

Width: k^2 + 7

Required

Area of the rectangle

The area of a rectangle is calculated as thus;

Area = Length * Width

By substituting k^2 + 3 for height and k^2 + 7 for width; This gives

Area = (k^2 + 3)(k^2 + 7)

Expand the bracket

Area = k^2(k^2 + 7) + 3(k^2 + 7)

Open each bracket

Area = k^2*k^2 + k^2*7 + 3*k^2 + 3*7

Area = k^4 +7 k^2 + 3k^2 + 21

Area = k^4 +10 k^2 + 21

Hence, the area of the rectangle in polynomial form is k^4 +10 k^2 + 21

Solve x^2 + 2x - 48 = 0
Georgia [21]

Answer:

x = - 8, x = 6

Step-by-step explanation:

{x}^{2}  + 2x - 48 = 0 \\  \\  {x}^{2}  + 8x - 6x - 48 = 0 \\  \\ x(x + 8) - 6(x + 8) = 0 \\  \\ (x + 8)(x - 6) = 0 \\  \\ x + 8 = 0 \:  \: or \:  \: x - 6 = 0 \\  \\ x =  - 8, \:  \:  \:  \: x = 6 \\

Please help me with math<br> i need it soon
AnnyKZ [126]
Lets get started :)

We are told that Mrs. Thymes is buying mulch for her gardens.

Let us check the price for each option:

\boxed {Option \ A}
3 yd³ for $165
Divide 165 by 3, to find the price per cubic yard:
\frac{165}{3} = $55 per cubic yard

\boxed {Option \ B }
4 yd³ for $240
Do the same:
\frac{240}{4} = $60 per cubic yard

\boxed {Option \ C }
6 yd³ for $300
\frac{300}{6} = $50 per cubic yard

\boxed {Option \ D }
8 yd³ for $360
\frac{360}{8} = $45 per cubic yard

Therefore, we can see that 8 yd³ for $360 is the best price

\boxed {Your \ Answer \ will \ be \ Option \ D }
