I’m pretty sure it’s c
Explanation
Answer:
94
Step-by-step explanation:
PEDMAS

Step 1 : Multiplication :
-6×3 =-18
Step 2: Addition: -18+78 = +60
Step 3: Addition : 35+60
= 94
Vertex form is
y = a(x - b)^2 + c
here a = -3 and b = -18 so we have
y = a(x + 3)^2 - 18
when x = 0 , y= 0 ( the y-intercept) so:-
0 = a(3^)2 - 18
9a = 18
a = 2
so the parabola is y = 2(x + 3)^2 - 18
x intercepts found as follows:-
2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 = +/- sqrt9 = +/- 3
so x intercepts are 0 and -6 Answer
Answer:
<CAD would also be 58°
Step-by-step explanation:
Because sides AB, DC, AD, and BC are congruent that means that all opposite angles will be congruent(equal too)
