Use properties to find the sum or product 93 + (68+7)
2 answers:
The sum :93 + (68+7) = <u><em>168</em></u>
<h3>Further explanation</h3>Calculation operations include multiply, divide, add, substract, etc.
In mathematical operations we can use the order of operation / calculation according to the principle of <em>PEMDAS</em>
- P: Parentheses ⇒ ( )
- E: Exponents (powers, square roots, etc.)⇒√,²
- MD: Multiplication and Division ⇒ x and :
- AS: Addition and Subtraction ⇒ + and -
Multiplication and division or addition and subtraction are interchangeable/rank equally so the calculations/equation operations should be done from left to right
The sum or product 93 + (68 + 7)
From this problem, we can know that the calculated operation used is only an addition, so that the form of parentheses has no effect, but we still adjust to the guidelines in <em>PEMDAS</em> that we count the calculation operations in parentheses first
then :
6 squared divided by 2 (3) +4
an algebraic expression
Keywords: PEMDAS, arithmetic operations, multiply, divide, add, substract

Substitute this into the parabolic equation,
We're told the line intersects
twice, which means the quadratic above has two distinct real solutions. Its discriminant must then be positive, so we know
We can tell from the quadratic equation that has its vertex at the point (3, 6). Also, note that
and
so the furthest to the right that extends is the point (5, 2). The line
passes through this point for
. For any value of
, the line
passes through
either only once, or not at all.
