After simplification, the answer would be h = 624.
If you substituted 2 for t, you would see that h would get smaller. Each time you increased t, h would get smaller.

The solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7
<h3>How to determine the solution set of the equation?</h3>
The equation is given as:
x^2 + 2x - 48 = 0
A quadratic equation is represented as:
ax^2 + bx + c = 0
By comparing both equations, we have
a = 1, b = 2 and c = -48
The solution of the quadratic equation is then calculated using
x = (-b ± √(b^2 - 4ac))/2a
Substitute values for a, b and c in the above equation
x = (-2 ± √(2^2 - 4 * 1 * -48))/2 * 1
This gives
x = (-2 ± √196)/2
Evaluate the square root of 196
x = (-2 ± 14)/2
Divide through by 2
x = -1 ± 7
Hence, the solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7

"the product of" ⇒ ___ * ___
86 ⇒ 86 . . . . . fills first blank
and
the depth of the river ⇒ d . . . . . fills second blank.
Your expression is
86 * d
Answer:
x is equal to 30
<ABC is equal to 100°
<DBC is equal to 80°
Step-by-step explanation:
3x +10 +2x +20 =180
5x = 180 - 10- 20
5x = 150, divide both sides by 5
x is equal to 30
<ABC = 3x + 10 = 3 × 30 + 10 = 100°
<DBC = 180 - <ABC = 180 - 100 = 80°
C is the correct answer
dilation will change the shape and it will not be congruent
