PLEASE HELP ME ANSWER THIS!!

Answer:

Is this what you meant?

(2x + 3x) × (3 + 15) = 12x + 36

(5x) × (18) = 12x + 36

90x = 12x + 36

78x = 36

x = 36 / 78

x = 18 / 39

_____________________

or

3(2x+3x) + 15 = 12x + 36

10x + 15 = 12x + 36

-21 = 2x

2x = -21

x = -21/2

Answer:

2x = 80. On dividing both sides by 2, we obtain. x = 40. x + 15 = 40 + 15 = 55. Hence ... Let the three consecutive multiples of 8 be 8x, 8(x + 1), 8(x + 2). Sum of ... Number after interchanging = 10 × 3x + x = 30x + x = 31x.

Answer:

33, 34, 35

Step-by-step explanation:

Semiprimes are the product of 2 prime numbers, then

11 × 3 = 33

17 × 2 = 34

7 × 5 = 35

Step-by-step explanation:

f(-3)=(-3)^2+4

=9+4

=13

hope it helps u dear friend

Answer:

Step-by-step explanation:

Given

f(x) = x² + 4

Now

f(- 3) = (-3)² + 4

       = 9 + 4

       = 13

Answer:

C

Step-by-step explanation:

Pythagorean theorem = a² + b² = c²

Answer:

C.

Step-by-step explanation:

Pythagrean Theorem is on C

Step-by-step explanation:

The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.

The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).

In this case it is a cube root

Answer:

No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.

Step-by-step explanation:

Answer:

72.33

Step-by-step explanation:

45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

Answer:

[tex]y=\frac{3}{2} x+1[/tex]

Step-by-step explanation:

What we need to know:

1) Find the slope of line P

The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.

We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.

Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].

Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=\frac{3}{2} x+b[/tex]

2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex]  to find the y-intercept (b)

[tex]y=\frac{3}{2} x+b[/tex]

Plug in point Q (2,4)

[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]

Subtract 3 from both sides

[tex]4-3=3+b-3\\1=b[/tex]

Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:

[tex]y=\frac{3}{2} x+b[/tex]

[tex]y=\frac{3}{2} x+1[/tex]

Answer:

y = -5/2x + 6

Step-by-step explanation:

y = -5/2x + b

-4 = -5/2(4) + b

-4 = -10 + b

Answer:

3.5

Step-by-step explanation:

so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.

[tex]\frac{x}{2.5}[/tex] = [tex]\frac{7}{5}[/tex]

x×5=5x

2.5×7=17.5

5x=17.5

x=17.5/5

x=3.5

Answer:

3√2

Step-by-step explanation:

the 2nd answer

y=3√2

Answer:

Step-by-step explanation:

<JKL = 90 ( being inscribed angle in semi circle )

< JKP = 38 ( Inscribed angles on same arc are equal )

So now

<PKL = <JKL - < JKP

        = 90 - 38

        = 52

FINALLY

ARC PL = 2 * < PKL (Relation between arc and inscribed angle )

ARC PL = 2 * 52

             = 104

hope it helps :)
