(5a-2)(5a+2)-3(1-a)-3a=

Answers

Answer 1
Answer: So first we need to know the order of operations
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction

Then the special cases:
(I have attached a picture below)

Lets get into action!
(5a - 2)(5a + 2) - 3( 1 - a ) - 3a 
25a² - 4 - 3 + 3a - 3a 
25a² - 7 
25a² - 7 is the answer


Answer 2
Answer: Hi There! :)

(5a-2)(5a+2)-3(1-a)-3a=25a2−7

Therefore answer is 
25a2−7

The table displays the distribution of blood types A, B, AB, and O to the presence of the Rh factor that is either present (Pos.) or absent (Neg.). A 6-column table has 3 rows. The first column has entries negative, positive, total. The second column is labeled A with entries .07, .33, .40. The third column is labeled B with entries .02, .09, .11. The fourth column is labeled AB with entries .01, .03, .04. The fifth column is labeled O with entries .08, .37, .45. The sixth column is labeled Total with entries .18, .82, 1.0.

What is the slope of a line parallel to the line -3x+5y=-10

Answers

This looks familiar, right? Like slope-intercept.

y=mx+b, where m is the slope.

Let's right it like that.

5y=3x-10 (add 3x to both sides, since we want to isolate the y.)

Now divide by 5, since - again - we want to isolate the y.

y= 3/5x-10/5 >>>> y= 3/5x-2

I think the slope is 3/5.

If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.

The slope can be found re-writting the function in the general format s y=mx+n where m is known as slope. For this case:

-3x+5y=-10, trasponding the x term

5y=3x-10, dividing by 5

y=3x/5-10/5, solving finally have the general format:

y=3/5x-2

Then the slope is the number that precede the x unknow.

Solution. The slope is 3/5.

Natalia constructed a right triangle with two side lengths measuring 3 and 5 units. She constructed a second right triangle similar to the first one, with the two corresponding sides measuring 5.1 and x units in length, respectively.What is the missing length, x, of the second triangle?

Answers


to start, you would divide 5.1 by 3 to find the scale factor. then you simply multiply that number(1.7) times 5, and get 8.5
(1.7) times 5, and get 8.5 hope i helped

A cell boat sale has three sides that are all the same links. Each side measure x-10. The sails perimeter is 63 units PLEASE HELP QUICKLY

Answers

Answer:

x=31

Step-by-step explanation:

x-10+x-10+x-10=63 (equation)

3x-30=63 (combine like terms)

3x=93 (combine like terms again)

x=31 (divide both sides by 3)

Sketch a plane containing points E,D, and B; where E and B are collinear with A , and D is a vertex where CD and FD meet. PLEASE HELP.

Answers

Solution:

we have been asked to sketch a plane containing points E, D and B.

where E and B are collinear with A. It mean all thses three points will fall on a straight line. Also D is a vertex where CD and FD meets.

The sketch has been attched below.

Here as you can see three points are in a staright line and we have another one in whuch two vectors CD and FD are meeting at the vertex D.
