11. The total area of a quilt is defined as the equation: A = x² + 13x + 36. Find the possible side

Luda [366]

Answer:

(x + 9)(x4)

Step-by-step explanation:

$A = {x}^{2} + 13x + 36 \\ \\ = {x}^{2} + 9x + 4x + 36 \\ \\ = x(x + 9) + 4(x + 9) \\ \\ = (x + 9)(x+4)$

So, the possible side

lengths of the quilt are (x + 9) and (x + 4) units.

15 = -3(2c + d) (Solve for c)

Paha777 [63]

Answer:

(15+3d)/6 = c

2 1/2 + 1/2d = c (more simplified)

Step-by-step explanation:

15 = -3(2c +d)

15 = -6c -3d

+3d +3d

15 +3d = -6c

/-6 /-6

(15+3d)/6 = c

How much greater is the weight of the large box at 3/4lb than the small box at <br> 1 1/8lbs

spin [16.1K]

Well, is just their difference, let's first convert the mixed fraction to "improper" and then subtract.

$\bf \stackrel{mixed}{1\frac{1}{8}}\implies \cfrac{1\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{9}{8}}\\\\
-------------------------------\\\\
\cfrac{9}{8}-\cfrac{3}{4}\impliedby \textit{our LCD is then 8}\implies \cfrac{(1\cdot 9)~~-~~(2\cdot 3)}{8}
\\\\\\
\cfrac{9-6}{8}\implies \cfrac{3}{8}$
