Answer:

a) x(2x-3)

x=width

b) 6x-6

A EXPLANATION

y: length

x: width

Length+3=2Width

y+3=2x

y=2x-3

x times y = area

x(2x-3) = area

B EXPLANATION

x=width

2x-3=length

x+x+(2x-3)+(2x-3)

Triangle ptg has side lengths of 18 27 cm and 13 cm what type of triangle is it
diamong [38]
Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.

The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).

A ramp is built in the shape of a right triangleThe hypotenuse of the ramp is 17 ft and the length of one leg is 8 ft. What is t
rjkz [21]

Answer:

B

Step-by-step explanation:

We can easily solve this problem by using the Pythagorean Theorem.

The Pythagorean Theorem says:

One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2

<u>Note:</u> This theorem holds true for right triangles

This problem is in fact of a right triangle as said. So we use the theorem to find the other leg's length.

One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2

8^2 + Another Leg ^ 2 = 17^2

64 + Another Leg ^ 2 = 289

Another Leg ^ 2 = 289 - 64

Another Leg ^ 2 = 225

The other is the square root of 225, which is 15

The correct answer is B

-4(-6y – 3) = 12 What is the value of y?
lozanna [386]

Answer:

y=0

Step-by-step explanation:

So you would do -4(6y-3) and divide that by -4

then you would do 12 and divide that by -4

or

You could do

-6y-3 which equals -3

then

add three to both sides like this -6y-3+3=-3+3

then simplify it to -6y=0

then divide -6y over -6 and 0 over -6

then it will simplify to 0
