The answer to this problem is -10x^2t-6st to get this answer or this problem you must use the product rule formula x^a x^b=x^a=b
Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5

Answer:
<h2>
150 ft tall</h2>
Step-by-step explanation:
first, lets first convert 2ft 6in to ft:
since ft=12 in, 6=0.5 ft
thus, the height of the birdbath is 2+0.5 ft=2.5ft
now, lets convert 18 inch shadow to ft:
since ft=12 in, 18=1.5 ft
now, we can use the following proportions to solve this problem:
2.5/1.5=x/90
1.5x=90*2.5
1.5x=225
x=225/1.5
x=150
Thus, the oak tree in the garden is 150 ft tall
