⨠ use the distributive property

$\sf{7x-3(x-6)=30}$

$\sf{7x-3x+18=30}$

⨠ combine like terms

$\sf{4x+18=30}$

⨠ subtract both sides by 18

$\sf{4x=30-18}$

$\sf{4x=12}$

⨠ divide both sides by 4

$\boxed{\sf x=3}$

The average speed of one airplane is 200 mph faster than that of an automobile. If the automobile starts at 3 a.m. and the airpl

Svetlanka [38]

Answer:

Distance = 500 miles

Step-by-step explanation:

Step 1: Write the data of speed, distance and time for aeroplane and automobile.

Automobile:

Speed = r

Time = 10 hours (3 am till 1 pm)

Distance = SxT

Distance = r x 10 = 10r

Aeroplane:

Speed = 200 + r (200 mph more than automobile)

Time = 2 hours ( 11 am till 1 pm)

Distance = SxT

Distance = 2x(200+r) = 400+2r

Step 2: Equate both distances to find the value of r

Distance of automobile = Distance of aeroplane

10r = 400 + 2r

8r = 400

r = 50

Step 3: Find the distance using any one equation

Distance of automobile = 10r

r = 50

Distance = 10 x 50 = 500 miles

Therefore, the plane travels 500 miles.

Which equation is quadratic in form?

Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

$ax^{2} + bx + c = 0$

case a) $6(x + 2)^{2} + 8x + 2 + 1 = 0$

$6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\ b=32\\ c=27$

The case a) is a quadratic equation

case b) $6x^{4} + 7x^{2} - 3 = 0$

The case b) is a grade $4$ polynomial

case c) $5x^{6} + x^{4} + 12 = 0$

The case c) is a grade $6$ polynomial

case d) $x^{9} + x^{3} - 10 = 0$

The case d) is a grade $9$ polynomial

therefore

the answer is

$6(x + 2)^{2} + 8x + 2 + 1 = 0$

on the grid below, draw and label an aquarium shaped like a rectangular prism with a volume of 8,000 cubic inches. (Hint: A cube

n200080 [17]

If you want an aquarium in shape of a cube with volume of 8000, then use the formula for volume of cube to find the length of one side:
V = s^3
where
s = side length
Substitute,
8000 = s^3
s = cuberoot(8000)
s = 20 inches

Well, if you have to draw this on a graphing paper, you should first make a scale to fit the drawing, like 1 inch = 0.5 cm, so a side length of 20 inches is equivalent to 10 cm on your graphing paper.

Hope this helped!
