5 times the sum of s and 7

EastWind [94]

Answer:

5(s+7) or (s+7)*5

Step-by-step explanation:

Read the question carefully when trying to do these problems. Whenever it states "sum" then you should automatically put the terms behind it (s and 7) together to add them together. This would look like s+7.

Next it says 5 TIMES the sum of the terms therefore you should put s+7 together in parentheses and multiply them by 5 so that you first have the sum of s and 7 in parentheses. This would then look like 5(s+7) or (s+7)*5.

Write an equation for the problem and then solve.

AVprozaik [17]

Answer:

first rectangle: 18 by 9
second rectangle 21 by 6
x = 9

Step-by-step explanation:

The perimeter in each case is double the sum of the side dimensions. Since the perimeters are equal, the sum of side dimensions will be equal:

2x +x = (x +12) +(x -3)

3x = 2x +9 . . . . . . . . collect terms

x = 9 . . . . . . . . . . . . . subtract 2x

Given this value of x, the dimensions of the first rectangle are ...

{2x, x} = {2·9, 9} = {18, 9}

And the dimensions of the second rectangle are ...

{x+12, x-3} = {9+12, 9-3} = {21, 6}

A straight fence is constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. A certain fence begins a

Ket [755]

Answer: 72 ft

Step-by-step explanation:

Given

The width of a post is $w=6\ in.$

Posts are separated by $5\ ft$ chain

for 2 posts, length is $6+5+6=17\ ft$

for 3 posts, length is $6+5+6+5+6=28\ ft$

for 4 posts, it is $28+5+6=39$

i.e. 11 ft is adding on the addition of another post

for 7 posts it is $17+11\times 5=72\ ft$

Thus, the total length of the fence is $72\ ft$

A wooden log 10 meters long is leaning against a vertical wall with its other end on the ground. The top end of the log is slidi

Andre45 [30]

Answer:

Step-by-step explanation:

This is a related rates problem from calculus using implicit differentiation. The main equation is Pythagorean's Theorem. Basically, what we are looking for is $\frac{dx}{dt}$ when y = 6 and $\frac{dy}{dt}=-2$ .

The equation for Pythagorean's Theorem is

$x^2+y^2=c^2$ where x and y are the legs and c is the hypotenuse. The length of the hypotenuse is 10, so when we find the derivative of this function with respect to time, and using implicit differentiation, we get:

$2x\frac{dx}{dt}+2y\frac{dy}{dt}=0$ and divide everything by 2 to simplify:

$x\frac{dx}{dt}+y\frac{dy}{dt}=0$ . Looking at that equation, it looks like we need a value for x, y, $\frac{dx}{dt}$ and $\frac{dy}{dt}$ .

Since we are looking for $\frac{dx}{dt}$ , that can be our only unknown and everything else has to have a value. So what do we know?

If we construct a right triangle with 10 as the hypotenuse and use 6 for y, we can solve for x (which is the only unknown we have, actually). Using Pythagorean's Theorem to solve for x:

$x^2+6^2=10^2$ and
