122 =x
Answer:
ax²+bx+c
ax²+bxy+cy²
Step-by-step explanation:
A quadratic expression is one where the maximum degree of the variable or variables ( in case of more than one variable the sum of the degree of the variables in a single term considered) is 2.
For example:
A quadratic expression of a single variable is ax²+bx+c {Where a, b, and c are the arbitrary constants}
A quadratic expression with two variables is ax²+bxy+cy² {Where a, b, and c are the arbitrary constants}
And, a quadratic expression with three variables is ax² +by² +cz² +dxy +eyz +fzx {Where a, b, c, d, e, f are the arbitrary constants} (Answer)
Answer:
Zach can send at most 100 messages, or if x is how many messages, x≤100
Step-by-step explanation:
We will start by putting the amount of money Zach's limit has into cents. This will be 1000 cents. We will also put how much money Zach uses per message as cents, which will be 10. Now here is the first inequality you can make with this information
10x≤1000
From here you divide both sides of the inequality by 10 and get
x≤100
This is the final inequality, and it means Zach can send less than or equal to 100 messages
A cube has all the sides equal.
A diagonal then acts as the hypotenuse of a face such that,
Sin 45° = Side/hypotenuse = Side/12.8 => Side = Hypotenuse * Sin 45 = 9.05 in
Volume = base*width*height = sides^3 (since all sides are equal) = 9.05^3 =741.22 in^3
To nearest tenth,
Volume = 741.2 in^3 {and correct answer is A)}
244 56/70 = 244 (56 ÷ 14)/(70 ÷ 14) = 244 4/5
