Answer:

length: 16 m; width: 13 m

Step-by-step explanation:

Write each of the statements as an equation. You know that the formula for the perimeter is ...

P = 2(L +W)

so one of your equations is this one with the value of P filled in:

• 2L + 2W = 58

The other equation expresses the relation between L and W:

• L = W +3 . . . . . . . . the length is 3 meters greater than the width

There are many ways to solve such a system of equations. Since you have an expression for L, it is convenient to substitute that into the first equation to get ...

2(W+3) +2W = 58

4W +6 = 58 . . . . . . . simplify

4W = 52 . . . . . . . . . . subtract 6

W = 13 . . . . . . . . . . . .divide by 4

We can use the expression for L to find its value:

L = 13 +3 = 16

The length is 16 meters; the width is 13 meters.

Explain he differences between properties of equality and properties of inequality when solving equations and inequalities.

nadya68 [22]

The difference between properties of equality and properties of inequality that you need to take into account when you are solving equalities and inequalities is the effect that some operations have on the sign.

1) The multiplicative property of equality permits you to multiplicate both members (sides) on an equality times a factor and the equality will remain. But in an inequality, while the factor is positive the inequality will remain but when the factor is negative, the sign of the inequality will change.

2) The same is true about the division property:

3) When you use othe functions like absoulte value and square root you will also need to be attentive of the effect of the function on the sign of the equality,.

Suppose g(x)=f(x+2)-3

kap26 [50]

The transformations which map f(x) to g(x) according to the equation are; Translation of f(x) 2 units to the left and 3 units upwards.

<h3>Which translations maps f(x) to g(x)?</h3>

The equation given in the task content is as follows;

g(x)=f(x+2)-3

It therefore follows that the transformations which would produce function g(x) from f(x) involves a 2 units translation to the left and a 3 units translation upward.

Remarks:

The complete question requires that the transformations from f(x) to g(x) be identified.

Solve the equation for C<br><br> R-C=P

earnstyle [38]

Answer:

C = R - P

add C to both sides of the equation

R = P + C

subtract (P) from both sides

R - P = C ⇒ C = R - P

M+2 1/4=8 4/5 pls show your work . A) 6 3/1 B) 11 1/20 C) 6 11/20 D) 6 9/20

Neko [114]

Please include the instructions. It appears that you want to find the value of m that makes m + 2 1/4 = 8 4/5, but you should state this explicitly.

Rewrite m + 2 1/4 = 8 4/5 as m + 2.25 = 8.80.
Subtr. 2.25 from both sides: m = 6.55 (answer)

This is also equal to 131/20 or 6 11/20.

Next time, would you please insert punctuation in your list of answers, to separate A from B, B from C, and so on.
