0=x^2-3x-28 gives x=7 or x=-4. These are the x-intercepts. The y-intercept is when x is 0. y=(0)^2-3(0)-28. The y-intercept is -28.
Answer:
Step-by-step explanation:
5x + 10 - 3x = 2x - 10
2x + 10 = 2x - 10
0x = -20

Answer:
a^2+b^2 = x^2
Step-by-step explanation:
We can use Pythagorean theorem
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
If x is your hypotenuse
a^2+b^2 = x^2
Since you already simplified it but made a mistake 2(7+4)+10(2x4)=2(11)+10(8)=22+80=102. So the answer is 102. Hope this helped.
Answer:
4. 52 ft^2
5. 25 ft^2
Step-by-step explanation:
15 -11 To get the width of scrapbooking which is = 4
4 * 13 = 52 ft^2
9 - 4 = 5 ft
5 * 5 = 25ft
