Answer 1

Answer:

d + 85

Step-by-step explanation:

Look at it like this,

suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS

or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.

notice that you always take the number of DVDs you already have, and add 85 to it.

d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards

Use factoring to find the zeros of the following function:
f(x)=5x^3-7x^2-45x+63​

Answers

Answer:

-3, +3, 7/5

Step-by-step explanation:

(5x³-7x²)+(-45x+63)=0

X²(5x-7)-9(5x-7)=0

(X²+9)(5x-7)=0

Either x²-9=0

X²=9 so x=+3 and -3

Or 5x-7=0

5x=7 so x=1.4 (or 7/5)

Since the big block has an area of X^2, then this shows the sides to be X.

This gives the sides of the block with area X to be 1 and X.

on a map with a scale 1: 25000,the area of a lake is 33.6 square centimeters. calculate the actual area of the lake, giving your answer in square kilometers​

Answers

Given :

On a map with a scale 1: 25000 .

The area of a lake is 33.6 square centimeters.

To Find :

The actual area of the lake.

Solution :

Let, actual area of lake is A.

So,

[tex]\dfrac{33.6}{A}=\dfrac{1}{25000}\\\\A = 840000\ cm^2[/tex]

We know , [tex]1 \ cm^2 = 10^{-10}\ km^2[/tex]

Area in km² is :

[tex]A = 840000\times 10^{-10}\ km^2\\\\A = 8.4 \times 10^{-5}\ km^2[/tex]

Hence, this is the required solution.
