In complex calculations like this, the precedence goes like this

B = Brackets
O = Of (or Exponent)
D = Division
M = Multiplication
A = Addition
S = Substraction

So, in your formula, it will go like this

1/2x3+1/4x2
= 0.5 x 3 + 0.25 x 2
= 1.5 + 0.5
= 2

Hope this helps.

Can you make an equilateral right triangle

Tcecarenko [31]

No you can't
Because in an equilateral triangle all sides and angles must be equal and for that all angles must equal 60 degrees so that their sum is 180 degrees, but a right triangle requires an angle of 90 degrees which the equilateral triangle doesn't have, so there's no such thing as an equilateral right triangle.

aliya0001 [1]

Question:

A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?

Answer:

$200 + 25x < 750$

Number of seats in a row must be less than 22

Step-by-step explanation:

Given

Total = Less than 750

Current Seats = 200

Rows = 25

Seat per row = x

Required

Represent as an inequality

The scenario will be represented as:

$Current\ Seats + Rows * x = Total$

Substitute 200 for Current Seats

$200 + Rows * x = Total$

Substitute 25 for Rows

$200 + 25* x = Total$

$200 + 25x = Total$

Substitute <750 for Total.

The equation then becomes

$200 + 25x < 750$

Solving further:

$25x < 750 - 200$

$25x < 550$

$x < \frac{550}{25}$

$x < 22$

This means that:

Number of seats in a row must be less than 22

Solve for x enter your answer in interval notation using grouping symbols x²+2x<8

statuscvo [17]

X^2 + 2x < 8 x^2 + 2x - 8 < 0 (x + 4)(x - 2) < 0 ,, {x + 4 < 0 and x - 2 > 0} or {x + 4 > 0 ,,and x - 2 < 0} ,, {x < -4 and x > 2} or {x > -4 and x < 2},, Discard x < -4 and x > 2 because it has no solutions, leaving just x > -4 and x < 2 ,, -4 < x < 2
