Answer:
2(j+4)
Step-by-step explanation:
D.) 0.5 seconds to 1.5 seconds.
Answer:
The answer is
<h2>1225</h2>
Step-by-step explanation:
4x² + 5 - 6x³ + 3x⁴ - x
x = - 4
Substitute the value of x into the expression
That's
4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4
Simplify
4(16) + 5 - 6( -64) + 3( 256) + 4
64 + 5 + 384 + 768 + 4
We have the final answer as
<h3>1225</h3>

Answer:
∠ ADC = 100° , ∠ DCB = 39°
Step-by-step explanation:
(3y + 7) and ( 3y - 13) are angles on a straight line and sum to 180° , so
3y + 7 + 3y - 13 = 180
6y - 6 = 180 ( add 6 to both sides )
6y = 186 ( divide both sides by 6 )
y = 31
Then
∠ ADC = 3y + 7 = 3(31) + 7 = 93 + 7 = 100°
and
∠ BDC = 3y - 13 = 3(31) - 13 = 93 - 13 = 80°
∠ BDC = 180° - (61 + 80)° ← angle sum in Δ BCD = 180°
= 180° - 141°
= 39°
