Answer: Multiply the lenght and the width of the scale drawing of rectangle by $\frac{8}{5}$

Step-by-step explanation:

Knowing that the scale factor used is:

$scale\ factor=\frac{5}{8}$

You know that the dimensions of the scale drawing was obtained by multiplying the dimensions of the original rectangle by $\frac{5}{8}$ .

Therefore, the dimensions of the original rectangle can be found with this method:

Multiply the lenght and the width of the scale drawing of rectangle by $\frac{8}{5}$

Then, you get:

$lenght_{(original)}=(\frac{8}{5})(18\ inches)\\\\lenght_{(original)}=28.8\ inches\\\\\\width_{(original)}=(\frac{8}{5})(12\ inches)\\\\width_{(original)}=19.2\ inches$

Explanation :

Given that:

In a box 25 cards are there and 1 to 25 numbers are written on them.

• One card is drawn randomly.

To Find:

• What is the probability that it is multiple of 5.

We know that:

P(E)= F/T

Where,

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

We have:

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

P(E)= 5/25

P(E)=1/5

Hence,

The probability that it is multiple of 5 is ⅕

Answer:

A. The solution set is x = 5 or -7

Step-by-step explanation:

$\sqrt[4]{ {x}^{2} + 2x } = \sqrt[4]{35} \\ {({x}^{2} + 2x) }^{ \frac{1}{4} } = {(35)}^{ \frac{1}{4} } \\ {x}^{ \frac{1}{2} } + {2x}^{ \frac{1}{4} } = {35}^{ \frac{1}{4} } \\ {x}^{2} + 2x = 35 \\ {x}^{2} + 2x - 35 = 0 \\ (x - 5)(x + 7) = 0 \\ x = 5 \: or \: - 7$
