Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
Answer:
61
Step-by-step explanation:
3x + 28
5x + 52
<u>+ 2x - 10 </u>
10x + 70 = 180º
x = 11
3(11) + 28 = 61º
<span>1 . (–2, –3) and (–4, 4)
d = </span>√(-4 - -2)^2 + ( 4 - -3)^2
d = √85<span>
2.Find the distance EA for the points E(–8, –2) and A(4, 1).
</span>d = √(4 - -8)^2 + ( 1 - -2)^2
d = 3√17<span>
3.Find the distance EA for the points E(2, 3) and A(4, 2).
</span>d = √(4 - 2)^2 + ( 2 - 3)^2
d = √5<span>
4. Find the distance between (0, 0) and (5, 8).
</span>d = √(5 - 0)^2 + ( 8 -0)^2
d = √89
