A carpenter is assigned the job of expanding a rectangular deck where the width is one-fourth the length. the length of the deck

anzhelika [568]

Alright, lets get started.

Suppose the original deck size: width = x feet

the width is one-fourth the length given in question means length = 4 x feet

Means the originally area = $x * 4 x = 4 x^{2}$

Now the dimensions are changed.

New dimensions, width = (x + 6)

new length = (4x+10)

So, new area will be = $(x+6) * (4x+10) = 4x^{2} + 10 x + 24 x + 60 = 4x^{2} + 34 x + 60$

the area of the new rectangular deck is 128 ft2 larger than the area of the original deck, means

$4x^{2} + 128= 4x^{2} + 34 x + 60$

Subtracting $4x^{2}$ from both sides

$128 = 34 x + 60$

Subtracting 60 from both sides

$128 - 60 = 34 x + 60 - 60$

$68 = 34 x$

Dividing 34 in both sides

$\frac{68}{34} = \frac{34 x }{34}$

$x = 2$

Means width = 2 feet

Length would be = 4 time width = 4 * 2 = 8 feet

Means dimension of original deck would be = 2 feet and 8 feet :Answer

Hope it will help :)

The slope of the line that passes through the points (-10,y) and (5, 2) is 2/5. What is the value of y?

Murrr4er [49]

Answer:

C, -4

Step-by-step explanation:

slope=change in y/change in x

$\frac{2 - y}{5 - ( - 10)} = \frac{2}{5}$

$\frac{2 - y}{5 + 10} = \frac{2}{5}$

multiply both sides by 2/5

$2 - y = \frac{2}{5} (5 + 10)$

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4

$2 - y = 2 + 4$

$2 - y = 6$

bring y to the other side by adding y on both sides

$2 = 6 + y$

subtract 6 on both sides

$2 - 6 = y$

so y is -4
