Answer:

D) -4x+14

Step-by-step explanation:

We are given with the expression

3 - (4x - 5) + 6

Here we are going to open the bracket at first step

as we have a negative sign in front of bracket the signs of the terms inside brackets will be reversed

3-4x+5+6

now we bring the like terms together

3+5+6 - 4x

Here 3, 5, 6 all are constant and hence like

14-4x

or

3 - (4x - 5) + 6= -4x+14

Hence our answer is -4x+14

A parallelogram is shown below:
Marina CMI [18]
<h3>Answer:</h3>

A:  6 ft²

B:  3 ft² is the area of each of the two congruent triangles

<h3>Step-by-step explanation:</h3>

Part A. As with a rectangle, the area of a parallelogram is the product of base length and height.

  Area = (8 ft)·(3/4 ft) = 6 ft²

___

Part B. If you cut the area into two halves, each half will have half the area of the original. (That should not be a surprise.)

  triangle area = (6 ft²)/2 = 3 ft²

If the triangles are created by a diagonal across the original figure, each will have a base length and height that is the same as that of the original figure. The area of a triangle is half the product of base and height, so each triangle will have area ...

  triangle area = (1/2)bh = (1/2)(8 ft)(3/4 ft) = 3 ft²

Solve for m/TRS if m/QRS = 88° and m/QRT = 54°.<br> ?<br> Answer: m/TRS =<br> Submit Answer
Citrus2011 [14]

The measure of the angle TRS is 34 degrees

<h3>Line and angles</h3>

The point where two lines meet is known as an angle

Given the following parameters

<QRS = 88 degrees

<QRT = 54 degrees

Using the expression

<QRS = <QRT + <TRS

Substitute the given parameters

88 = 54 + <TRS
<TRS = 88 - 54

<TRS = 34 degrees

Hence the measure of the angle TRS is 34 degrees

The weight of an adult blue whale is 9 × 104 kilograms; the weight of an elephant is 3 × 103 kilograms. How many times heavier i
kozerog [31]
To determine how many times one variable to another variable, we get the ratio of both by dividing the values. For this case, we divide the weight of whale and the weight of the elephant.

9 × 10^4 kilograms / <span>3 × 10^3 kilograms = 30 <------ OPTION 1</span>
