No order of operations is what you might know as Pemdas ,number of Operations is something iv'e never heard of.

Answer:

<em>No. </em>

Step-by-step explanation:

Because the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract from left to right.

Examples: 12+9*8÷2

Multiply and divide numbers from left to right.

\displaystyle 9\times8\div2

\displaystyle 9\times8=72

\displaystyle 72\div2=36

\displaystyle 36+12

Add numbers from left to right.

\displaystyle 36+12=48

\huge \boxed{48}, which is our answer.

The some of two consecutive even integers is 170. find the two integers.
Tatiana [17]
2 consecutive even integers : x and x + 2

x + x + 2 = 170
2x + 2 = 170
2x = 170 - 2
2x = 168
x = 168/2
x = 84

x + 2 = 84 + 2 = 86

so ur 2 numbers are 84 and 86

I SPENT 50 POINTS ON THIS, PLEASE HELP
Anestetic [448]

In the figure, we can consider that the base is the side that mesures 12 in and that the height is the side that measures 15 in, since that sides are perpendicular. So, we just need to use the given formula:

A = \dfrac{bh}{2}\Longrightarrow A = \dfrac{12\cdot15}{2}\Longrightarrow A=6\cdot15\Longrightarrow \boxed{A = 90~\text{in}^2}

Hence, the area of the triangle is 90 in² (B).
