vagabundo [1.1K]

Answer:

3x^{2} -2x +5=0

Step-by-step explanation:

Combine liked terms:

3x^{2}+5x+x-1x+6+2=7x+3

3x^{2}+6x-1x+8=7x+3

3x^{2}+5x+8=7x+3

Subtract 3: 3x^{2}+5x+8-3=7x+3-3

3x^{2}+5x+5=7x

Now subtract 7x:

3x^{2}+5x+5-7x=7x-7x

If you want combine liked terms:

3x^{2}-7x+5x+5=0

3x^{2}-2x+5=0

Hope this helps!

Plsss help meee 45 points plus brainliest
romanna [79]

<em>Hello There!!</em>

Let us call X the equal distances GH = HI = IJ

GH = X

HI = X

IJ = X

Note that HJ = HI + IJ, so

HJ = X + X

10 = 2X

X = 5

Well, We're looking at figure we can conclude that:

GJ + JK = GK

GJ = GH + HI + IJ

GJ = 15

GJ + JK = GK

15 + JK = 24

JK = 9

GH = X = 5

HI = X = 5

IJ = X = 5

JK = 9

HopeThisHelpsYou!

ASAP!!! I NEED HELP geometry/trigonometry please
777dan777 [17]

Answer:

Perpendicular = Y = 34.64 ft (Approx)

Base = X = 20 ft

Step-by-step explanation:

Given:

θ = 60°

Hypotenuse = 40 ft

Perpendicular = Y

Base = X

Find:

X and Y

Computation:

Sinθ = Perpendicular / Hypotenuse

Sin 60 = Y / 40

Perpendicular = Y = 34.64 ft (Approx)

Cosθ = base / Hypotenuse

cos 60 = X / 40

Base = X = 20 ft
