Answer:
a=45 b=65
Step-by-step explanation:
You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above
Answer: t = -18/7 = 2.57
Step-by-step explanation:
-Solve for t:
Answer:
well ig thats good
Step-by-step explanation:
thanks
Given the quadratic equation ax^2 + bx + c = 0, the coefficients of x^2, x and 1 are a, b and c respectively.
(a) and (b) are not valid quadratics, because they omit the exponent 2. Rewrite these as comments within your original post, please.
(c) 4x^2+20x+25=0: Here, a = 4, b = 20 and c = 25.
