Answer:
14
Step-by-step explanation:
Even though the triangle is "upside down"
a = (1/2)bh
b is QB = 4
h is QA = 7
a = (1/2) * 4 * 7
a = 14
Ummm not to freak you out but what’s that in the background?
Answer:
f = 
Step-by-step explanation:
1. 4(4f - 9) = -(2-f) distribute the negative
2. 4(4f - 9) = -2 + f Distribute the 4
3. 16f - 9 = -2 + f Subtract f on both sides
4. 15f - 9 = -2 Add 9 on both sides
5. 15f = 7 Divide both equations by 15
6.
f = 
Step-by-step explanation:
Assume that
