Answer:

\boxed {\boxed {\sf No}}

Step-by-step explanation:

If a triangle is a right triangle, it can satisfy Pythagorean Theorem.

a^2+b^2=c^2

where a and b are the legs and c is the hypotenuse.

12 and 84 are the legs because are they shortest. 85 is the hypotenuse because it is the longest side.

a= 12 \\b=84 \\c=85

Substitute the values into the formula.

(12)^2+(84)^2=(85)^2

Solve the exponents.

  • 12²= 12*12=144
  • 84²=84*84=7056
  • 85²= 85*85=7225

144+7056=7225

Add on the right side.

7200\neq 7225

7220 is not equal to 7225, so these sides cannot be a right triangle.

32x2 – 24x = 0<br> What’s the answer to this?
Vlad [161]

Answer:

x=0      x = 3/4

Step-by-step explanation:

32x^2 – 24x = 0

Factor out 8x

8x(4x -3)

Using the zero product property

8x = 0   4x-3 =0

x=0       4x=3

x=0      x = 3/4

WILL GIVE BRAINLIEST IF RIGHT<br> how do you find the growth factor of a graph
notsponge [240]

Answer:

The growth "rate" (r) is determined as b = 1 + r.

Step-by-step explanation:

A growth factor is the factor by which a quantity multiplies itself over time. When trying to find the growth rate, you have to remember that the original exponential formula was y = ab^x. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.

Please mark me the brainliest!?!
