Well there’s 180° in one triangle. a right angle is 90°. 2x+3x+90=180. 5x=90 divide by five, x=18°
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)
m = 
= 
= - 1
If you want to multiply (2*x + 5) and (2*x - 5), you can do this using the following steps:
(2*x + 5) * (2*x - 5) = 4*x^2 - 10*x + 10*x - 25 = 4*x^2 - 25
The correct result is 4*x^2 - 25.
30% as a decimal is 0.3
Multiply 780 by 0.3
780(0.3)=234 female doctors
Y^3 * y^5 = y^8. you add the exponents
