Step-by-step explanation:
can you translate it to engish, i might help!
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7
Answer:
<em>15</em>
Step-by-step explanation:
9x - 3 =
2(9x - 3) = 5x + 1 + 19
18x - 6 = 5x + 20
13x = 26
x = 2
<em>GH</em> = 9(2) - 3 <em>= 15</em>
