The correct answer is 14.
Answer:
Example Question: f(x) = 2x^2 + 2x - 1
If the leading coefficient is positive, the graph will be opening up (U) if the leading coefficient is negative, the graph will be opening down (n)
Roots are the x-intercepts that help find the axis of symmetry (add the two roots together and divide the result by 2 to get the axis of symmetry)
To find the vertex, simply imput the axis of symmetry into the given equation.
And that’s about it.

Answer:
9, 32 and 36
Step-by-step explanation:
The perimeter of a triangle is the sum of all the sides. Since you know the perimeter and the expressions for each of the sides, you can set up an equation to solve for the variable and find the values of the other sides:
one side: '4 times the shortest side' = 4s
shortest side: 's'
third side: '23 more than the shortest side' = s + 23
perimeter = 77
Equation: 4s + s + (s + 23) = 77
Combine like terms: 6s + 23 = 77
Subtract 23 from both sides: 6s + 23 - 23 = 77 - 23 or 6s = 54
Divide by 6: 6s/6 = 54/6 or s = 9
one side: 4s = 4(9) = 36
shortest side: s = 9
third side: s + 23 = 9 + 23 = 32
83 + 58 = 141
55 + 68 = 123
92 + 69 = 161
48 + 72 = 120
69 + 77 = 146
95 + 88 = 183
78 + 43 = 121
86 + 77 = 163
79 + 47 = 126
74 + 59 = 133
85 + 94 = 179
69 + 78 = 147
91 + 89 = 180
48 + 95 = 143
66 + 45 = 111
73 + 86 = 159
98 + 74 = 172
23 + 79 = 102
163 - 125 = 38
243 - 74 = 169
208 - 92 = 116
262 - 77 = 185
122 - 86 = 36
197 - 82 = 115
159 - 41 = 118
299 - 151 = 148
181 - 87 = 94
196 - 159 = 37
232 - 168 = 64
165 - 76 = 89
241 - 85 = 156
149 - 38 = 111
184 - 95 = 89
124 - 67 = 57
142 - 96 = 46
272 - 119 = 153
261 - 95 = 166
225 - 88 = 137
p.s a calculator does exist.
