<h3>
Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
Answer:
Step-by-step explanation:
Easy the three angles of a triangle equal 180 degrees
so 60+75 = 135 --> 180-135=
1) 145
2) 35
3) no since the tops a 100 and its a Isosceles triangle two corners left it be 40 for each corner
4) 34 for both x's cause 34+34+112. = 180
5) 180- 120= 60- 10 = 50/4 is (12.5)= x
6) x = 15 cause it be 120- 60 to get 60
