Answer and Explanation:
I'm assuming you mean the "Additive property of equality".
The additive property of equality states if the same value amount is added to both sides of an expression or equation, it will remain equal.
Similarly, the additive property of inequalities states if the same value amount is added to both sides of an inequality, it will remain true.
The quadratic formula helps us solve any quadratic equation. First, we bring the equation to form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
This is proven and I’m positive this is what your asking! BRAINLIEST please
Answer:
HA = 16.2 m
DE = 17 m
Step-by-step explanation:
From the base of the cuboid, HDA will form a right angle triangle, where;
DA = 15 m
HA = 6 m
HA is the hypotenuse
Using pythagoras theorem;
HA = √(15² + 6²)
HA = √(225 + 36)
HA = √261
HA = 16.155 m
Approximating to 1 decimal place gives;
HA = 16.2 m
Similarly, HDE will also form a right angle triangle.
Thus;
DE = √((HD)² + (HE)²)
HD = 16.2 m
HE = 5 m
Thus;
DE = √(16.2² + 5²)
DE = 16.95 m
Approximating to 1 decimal place gives
DE = 17 m
Answer: D
Explanation: The function is an absolute value function with vertex at (-9,0). The slope of the part with x value greater than -9 is positive, and the slope of the part with x value less than -9 is negative.
Closest together means that the difference between the high and the low is the smallest.
Atlanta:
106 - -12 = 118
Boston:
103 - -19 = 122
Chicago:
100 - -32 = 132
Dallas:
111 - -8 = 119
The city that has the record high and low closest together is A) Atlanta.
Hope this helps!! :)
