Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2
The warmest recorded temperature is 214°F higher than the coldest temperature.
Since the sign of the two numbers are same, their final values will be added and the result will have the same signs as the two numbers (or the one with the greater absolute value). This is called the multiplicative property.
Expression for difference between the two temperatures is,
= 134−(−80)
By applying the multiplicative property of negative sign, we get
=134+80
= 214°F
Therefore, we conclude that the warmest recorded temperature is 214°F higher than the coldest temperature.

Answer:
1) 10
Basic facts:
<em>we can tell a right angle if there is a small square drawn where the angle measuring should be done</em>
Step-by-step explanation:
<u>Main step</u>
<u>90-60=30</u>
<u>30=3x</u>
<u>divide by 3</u>
<u>10 =x</u>
the value of x is 10
so option 1
