Simplify 24÷(-2)(3)+7 a. -29 b. 3 c. 11

a. -29

Step-by-step explanation:

The expression is:

24÷(-2)(3)+7

We can see that there is division, multiplication and addition involved. We will use the mathematical DMAS rule to solve the problem. So, division will be done first,

Division will give us:

24÷(-2)*(3)+7

= -12 * 3 + 7

After division, multiplication will be done:

Multiplication will give us:

= -36 +7

which equals to -29

So, option a is the correct answer ..

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
