Answer:

area =

Step-by-step explanation:

(4x+5)×3× = 12×^2+15

because

area = length × breadth

ans= 12x^2+15.

<h3>Multiplication Property of Equality is the missing reason</h3>

<em><u>Solution:</u></em>

Given that,

five thirds times x plus 2 equals negative 3

Therefore,

\frac{5}{3}x + 2 = -3

<em><u>Multiplication Property of Equality</u></em>

The Multiplication Property of Equality means that, if both sides of an equation is multiplied by same number, the equation still remains equal

\frac{5}{3}x + 2 = -3

Multiply both sides by 3

3(\frac{5}{3}x + 2) = -3 \times 3\\\\5x + 6 = -9

<em><u>Subtraction Property of Equality</u></em>

The Subtraction Property of Equality means that, we can subtract the same number from both sides of equation and the equation will still be true

5x + 6 = -9

Subtract 6 from both sides

5x + 6 - 6 = -9  - 6

5x = -15

<em><u>Division Property of Equality</u></em>

The Division Property of Equality means that, if both sides of an equation is divided by same number, the equation still remains true

5x = -15

Divide both sides by 5

x = -3

Murljashka [212]
Rate of growing, r = 91.2/90 = 1.013

Salary, f(x) = Initial salary * (r)^ (years from 2005)

f(x) = 90(1.013)^x.

This is the second option.

BC =using the Distance Formula
riadik2000 [5.3K]

Answer: Option A: 5

Step-by-step explanation:

If yo have the pairs (a, b) and (c, d)

The distance between these two points is:

distance = √( (a - c)^2 + (b - d)^2)

Here we want to find the distance between points B and C.

We can see that the coordinates of each one are:

point B: (-5, 5)

Point C: (-1, 2)

Then the distance between these points is:

AB = √( (-5 -(-1))^2 + (5 -2)^2) = 5

AB = √( 4^2 + 3^2)

Then the correct option is A

1058 rounded to the nearest hundred
GalinKa [24]

Answer:

1100

Step-by-step explanation:

Rounded to nearest hundred

Here we will tell you what 1058 is rounded to the nearest hundred and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 1058.

First, 1058 rounded to the nearest hundred is:

1100

When rounding to the nearest hundred, like we did with 1058 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
