Mathematics
1 answer:
Alex Ar [27]3 years ago
7 0

Step-by-step explanation:

Example: -2+-5

It can also be written as -2-5.

How I do these problems, I do 2+5, which is 7. Then I add a negative sign. So -2+-5 or -2-5 is equal to -7.

-a+-b can also be written as -a-b. So yes, if a and bare negative, then a + b is also negative.

hope it helps!

Solve 3 x - 9 x + 7 - 3 = -8.
erik [133]

Answer: x=2

3x−9x+7−3=−8

Step 1: Simplify both sides of the equation.

3x−9x+7−3=−8

3x+−9x+7+−3=−8

(3x+−9x)+(7+−3)=−8

−6x+4=−8

−6x+4=−8

−6x+4−4=−8−4

−6x=−12

−6x

−6

=

−12

−6

x=2

Question 15 of 28
mamaluj [8]

The length of LN in the triangle below is (LN)²=33²-11². It is obtained by applying the pythogorous theorem in the triangle MLN. Option A is correct,

<h3>What is the definition of a right-angle triangle?</h3>

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.

According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.

In triangle MLN applies the pythogorous theorem;

\rm h^2=p^2+b^2 \\\\ MN^2=ML^2+LN^2 \\\\ 33^2=11^2+LN^2 \\\\ LN^2=33^2-11^2

Hence option A is correct.
