Answer:
Step-by-step explanation:
<u>Given trinomial</u>
Let's try to factor 4t² - 9t + 2
<u>First find it's zeros:</u>
- t = (9 ± √9² - 4*4*2)/(2*4)
- t = (9 ± √81 - 32)/8
- t = (9 ± 7)/8
- t = 2 and t = 1/4
<u>So yes, it is factorable:</u>
- 4t² - 9t + 2 = 4(t - 2)(t - 1/4)
- or
- 4t² - 9t + 2 = (t - 2)(4t - 1)
<u>The given trinomial factored:</u>
Answer:
t = -14
Step-by-step explanation:
(t + 8)( - 2) =12
(t)(-2) + (8)(-2) = 12
-2t + -16 = 12
(subtract to make -16 positive)
-2t - 16 = 12
+16 +16
(add 16 to both sides. 16 and 12)
-2t = 28
(divide)
-2t = 28
/-2 /-2
t = -14

Answer:
-14x
Step-by-step explanation:
-4x+-10x =-14x
Answer : 35 brownies
==================================
working:
3/5 = 21
1/5 = 21 / 3
1/5 = 7
5/5 = 7 x 5
1 (the amount of brownies she brought) = 35
Therefore, she brought 35 brownies
