Serga [27]3 years ago
8 0

Answer:

so the sides would have to be equal for all sides

2x-3=3x-8    -3=x-8    x=5

x-12, 4x-1, neither, or both?

2x-3=x-12       x-3=-12      x=-9

4x-1=3x-8      x-1=-8      x=-7

2x-3=4x-1      -3=2x-1    -4 = 2x    x=-2

3x-8=x-12       2x-8=-12     2x=-4    x=-2

So the answer is neither or C

A certain right triangle has area 30 in. squared . one leg of the triangle measures 1 in. less than the hypotenuse. let x repres
Brut [27]
A) The length of the longer leg is x-1

b) Based on the area, the other leg is 2*30/(x -1). Based on the Pythagorean theorem, the other leg is √(x^2 -(x -1)^2).

c) Equating the two expressions for the shorter leg, we have
.. 60/(x -1) = √(2x -1)
.. 3600/(x -1)^2 = (2x -1)
.. (2x -1)(x^2 -2x +1) = 3600
.. 2x^3 -5x^2 +4x -3601 = 0

d) There is one positive real root, at x=13. A graphical solution works well.

The three sides of the triangle are 5 in, 12 in, 13 in.


_____
5-12-13 is a well-known Pythagorean triple. It is the next smallest one after 3-4-5.

An ice cream cone is 5" deep and 2" in top diameter. One scoop of vanilla ice cream, 2" in diameter, is placed on the cone. If t
Ratling [72]
If the total volume of the ice cream exceeds the internal volume of the cone, then it will overflow.

Volume of icecream = 4/3 * pi * r^3 = 4/3*pi*(1)^3 = 4.189 cu. in.Volume of cone = 1/3 * pi * r^2 * h = 1/3*pi*(1)^2*5 = 5.236 cu. in.

Since Volume of cone > Volume of icecream, the cone will not overflow.

the model represents the factorization of 2x2+5x+3. what are the factors of the polynomial.(2x+3)(x+1),(2x-3)(x-1),(3x+2)(x-1),(
Maurinko [17]

Answer:

The factors of the polynomial are (2x + 3)(x + 1) ⇒ 1st answer

Step-by-step explanation:

* Lets explain how to factor a trinomial in the form ax² ± bx ± c  

- Look at the c term first.  

# If the c term is a positive number, then its factors r , s will both  

  be positive or both be negative it depends on the sign of b, if b  

  positive then both are positive if b negative then both are negative  

# a has two factors h and k  

# The brackets are (hx ± r)(kx ± s) where a = hk , c = rs and b = rk + hs  

# If the c term is a negative number, then either r or s will be negative,  

  but not both.  

# a has two factors h and k  

# The brackets are (hx + r)(kx - s) where a = hk , c = rs and b = rk - hs  

* Lets solve the problem

∵ The trinomial is 2x² + 5x + 3

∴ a = 2 , b = 5 , c = 3

∵ c is positive

∴ Its factors r and s have same sign

∵ b is positive

∴ r and s both positive

∵ a = 2  

∵ The factors of a are h , k

∵ 2 = 2 × 1

∴ h = 2 and k = 1

∵ c = 3

∵ The factors of c are r , s

∵ 3 = 3 × 1

∴ r = 3 and s = 1

∵ The brackets are (hx + r)(kx + s)

∴ 2x² + 5x + = (2x + 3)(x + 1)

* The factors of the polynomial are (2x + 3)(x + 1)
