Answer:
D).
Step-by-step explanation:
ln (e · e^x) = x2 + 4x + 3
ln e^(x+1) = x^2 + 4x + 3
Taking all terms to the power e:
e^(x + 1 )= e^ (x^2 + 4x + 3)
x + 1 = x^2 + 4x + 3
x^2 + 3x + 2 = 0
(x + 2)(x + 1) = 0
x = -2, -1.
Answer:
12
Step-by-step explanation:
20² - 16² = x²
400 - 256 = x
400 - 256 = 144
√144 = 12
If the number before the place you are rounding to is a 5 or more you round up but if it is a 4 or below it stays the same so the answer is 28,000,000
t + 23 > 1 subtract 23 from both sides
t + 23 - 23 > 1 - 23
t > -22
Answer:
x = 98°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle and 53° and 45° are the opposite interior angles, hence
x = 53° + 45° = 98°
