I will convert feet to inches.
4 feet, 6 inches = 54 inches
20 feet = 240 inches
5/x = 54/240
Let x = closest height of tree
54x = 5(240)
54x = 1,200
x = 1200/54
x = 22.2222222222
The tree is about 22 feet tall.
Formula For Factoring Trinomials (when a =1)
It's always easaier to understand a new concept by looking at a
specific example so you might want to do that first. This formula works
when 'a' is 1. [ In other words, we will use this approach whenever the
coefficient in from of x2 is 1.
1) identify a,b, and c in the trinomial ax2 + bx+c
2) write down all factor pairs of c
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
The answer is C
-2× x＝ -2x
-2×-5＝10
2=9x+5 I think this is how you do it because you say that it have to equal to 2
Answer: d. 2.52
Step-by-step explanation:
5x = 30.16 - 17.56
5x = 12.6
X = 12.6/5 = 2.52
