Answer:

Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4
Answer: 5.88 feet tall
Step-by-step explanation:
Using this formula
Interest =principal×rate×time/100
Principal is the actual growth=3ft
Rate is the 32%
Time is 3yrs
Interest =3×32×3/100
Interest =2.88
To get the value for 3yrs,add the interest to the principal value
Exact value in 3yrs=
3+2.88
=5.88 feet tall

x,y - x,y-4
Step-by-step explanation:
x coordinates of a and b remain same but their y coordinates become -4
Answer:
-6(x-2)=-7(x-3) = False x = 9
Step-by-step explanation:
Solve for x:
-6 (x - 2) = -7 (x - 3)
Expand out terms of the left hand side:
12 - 6 x = -7 (x - 3)
Expand out terms of the right hand side:
12 - 6 x = 21 - 7 x
Add 7 x to both sides:
7 x - 6 x + 12 = (7 x - 7 x) + 21
7 x - 7 x = 0:
7 x - 6 x + 12 = 21
7 x - 6 x = x:
x + 12 = 21
Subtract 12 from both sides:
x + (12 - 12) = 21 - 12
12 - 12 = 0:
x = 21 - 12
21 - 12 = 9:
Answer: x = 9
