A. 19. You have to set them up equal to each other. So, 6x-2=4x+36. You then subtract the 4x from the 6x, and add 2 to 36. Which leaves you with 2x=38. Divide and you get 19! Hope this helps

Answer:

The vertex form is: y =  3(x-2)^2 + 7 . The vertex is (2, 7)

Step-by-step explanation:

Write the function: y = 3x^2 - 12x + 11 in vertex form

The vertex form of a quadratic equation is:

y = m(x - a)^2 + b where (a,b) is the vertex

For y = 3x^2 - 12x + 11

Solve for m

y = 3(x^2 - 4x) + 11

Complete the Square:

y = 3(x^2 - 4x + 4) + 11 - 4

y = 3(x - 2)^2 + 7

The vertex then is (2, 7)

Answer:

X^2 + 2(30x) + 900

Step-by-step explanation:

You multiply the sides of each square and add them to get the total of the whole square. For the top left square, you multiply x and x. For the top right, you multiply 30 and x. For the bottom left, you multiply 30 and x as well. And for the bottom right, you multiple 30 and 300. Add these together and you get X^2 + 2(30x) + 900.

Please help me guys ​

Step-by-step explanation:

midpoint : it is the point in the middle marking half of the total distance.

therefore,

1)

EV = LE = LV/2

10 = 5m

m = 2

2)

LR = RO = LO/2

n + 4 = 12

n = 8

3)

LER and LVO are similar triangles. that means they have the same angles, and the ratio of one corresponding pair of lines or sides between both triangles is the same for all corresponding line pairs.

we know e.g. LE/LV = 1/2.

the same ratio applies then to ER/VO = 1/2 = 18/20p.

18/20p = 1/2

18 = 20p/2

2×18 = 20p

36 = 20p

p = 36/20 = 9/5 = 1.88888888888...

4)

VL = 2×EL = 2×10 = 20

5)

LO = 2×RO = 2×12 = 24

6)

as we have already calculated for 3) :

VO = 36

7)

36 + 20 + 24 = 80

8)

10 + 12 + 18 = 40

9)

remember, the and angles in similar triangles.

LVO = 52°

10)

all angles around a single point in one side of a line are together 180°.

in this case there are 2 angles around E : LER and VER.

VER = 180 - LER = 180 - 52 = 128°
