Answer:
A and C
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x2+48x+144=52
Step 2: Subtract 52 from both sides.
4x2+48x+144−52=52−52
4x2+48x+92=0
For this equation: a=4, b=48, c=92
4x2+48x+92=0
Step 3: Use quadratic formula with a=4, b=48, c=92.
x=−48±√832/8
x=−6+√13 or x=−6−√13
–46
B.
46
B) (-1)(-1)(-1)(-1)
C) (-1)(-1)(-1)(-1)(-1)
D) (-1)(-1)(-1)(0)
i'm pretty sure it's C
-1 times -1 becomes positive, and then times -1 again, it's negative, and times it again, it's positive, and THEN one more time (lol) it's -1.
Answer:
To calculate the slope (m) between two points (x₁, y₁) and (x₂, y₂), you can use the formula:
\[ m = \frac{y₂ - y₁}{x₂ - x₁} \]
For the points (2,1) and (-3,4):
\[ m = \frac{4 - 1}{-3 - 2} = \frac{3}{-5} \]
Simplifying the fraction, the slope is:
\[ m = -\frac{3}{5} \]
2.a gas tank is 3.6 full. it takes 90 gallons to fill the tank. the total number of gallons the tank can hold is? 50, 89, 144 or 225?

Explanation:
Use the remote interior angle theorem. This says a pair of interior angles always add to the measure of the exterior angle that is not adjacent to any of the interior angles, so basically what your diagram is showing.
(interior angle C) + (interior angle D) = exterior angle
(46) + (-1+8x) = 18x+5
8x+45 = 18x+5
8x-18x = 5-45
-10x = -40
x = -40/(-10)
x = 4
