2 would be the answer if you follow your order of operations the order of operations is parentheses exponents multiply divide whichever comes first and add and subtract whichever comes first and -6x with the exponent of 2 it can be turned into -36 cuz you're multiplying six two times then 8 * 4 is 32 and 3 * 6 is 18 so you would do -36 + 32 which would give you negative 4 then you're going to bring down the 18 then do -4 + 18 which would give you 4 then you're going to bring down the - 6 and do 4-6 and -6 -4 gives you positive 2

Answer:

Distance of the keys on ground from the base of the tower = 7.38 ft

Step-by-step explanation:

Given:

Height of tower = 94 ft

Tower is leaning and makes an angle of 85.5 degrees from the ground.

Keys are dropped from the top of the tower.

To find the distance of the keys on ground from the base of the tower.

From the data given to us we can construct a right triangle ABC.

For the Δ ABC

AB= 94 ft

∠A= 85.5°

We can apply trigonometric ratio to find side BC which is the distance of the keys on ground from the base of the tower.

Using cosine ratio: $\cos\theta=\frac{Adjacent\ side}{Hypotenuse}$

In Δ ABC

$\cos85.5\°=\frac{AC}{AB}$

Multiplying both sides by AB.

$AB\cos 85.5\°=\frac{AC}{AB}\times AB$

$AB\cos 85.5\°=AC$

$AC=AB\cos 85.5\°$

Substituting value of AB and cos 85.5°

$AC=94\cos 85.5\°$

∴ $AC=7.38\ ft$

Distance of the keys on ground from the base of the tower = 7.38 ft

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.

IgorC [24]

B>a

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>

Answer:

<h2>This triangle is a right triangle:</h2><h2>36² + 15² = 39².</h2>

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

$a^2+b^2=c^2$
