The law of cosine is generally expressed as,
c² = a² + b² - 2ab x (cos C)
If the triangle is right (one of the angles measures 90 degrees, in this case C), the equation becomes,
c² = a² + b² - 2ab x (cos 90)
Since cos 90 is zero, this equation reduces to c² = a² + b². This equation is the general form of the Pythagorean theorem. Thus, the answer is TRUTH.

vladimir2022 [97]

Y= 250000-8750t

3.5 percent of 250000 is 8750, if that’s the amount decreasing each (t) years, you multiply that number by number of years taken into account.

Answer:

-4x-6x=-20=

x=2

-3(2x-3)=33=

x=-4

4x+3x+2x=180

x=20

Step-by-step explanation:

-4x-6x=-20

-4+(-6)=-10x

-10x=20 (divide both by 10)

x=-2 (divide by -1 to get positive)

x=2

-3(2x-3)=33

-6x+9=33

-9 . -9

-6x=24 (divide both by -6)

x=-4 (divide by -1 to make positive)

4x+3x+2x=180

(combine like terms)

9x=180 (divide both sides by 9)

x=20
