74% of 238 is 176.12

or 238 * .74 = 176.12.

Simplify 8(x+3)^2/2(x+3)

Answers

The simplification of the given expression [8(x+3)²]/[2(x+3)] is 4(x + 3).

What is an expression?

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that are all constrained and create an equation.

In other meaning, expression is beneficial to determine the end or root value of constraint.

As per the given expression,

[8(x+3)²]/[2(x+3)]

⇒ 8/2 × (x+3)²/(x+3)

⇒ 4(x+3)

Hence "The simplification of the given expression [8(x+3)²]/[2(x+3)] is 4(x + 3)".

8(x+3)^2/2(x+3)

[8(x + 3)(x + 3)]/2(x + 3)

8 ÷ 2 = 4

(x + 3)(x + 3) ÷ (x + 3) = (x + 3). In other words, we cancel one of the numerator factors.

Answer: 4(x + 3).

Which expression is equivalent to 27 + 45?8(3 + 6)
8(19 + 37)
9(3 + 5)
9(18 + 36)

Answers

Answer:

9 (3 + 5)

Step-by-step explanation:

The given expression is 27 + 45

We can write both terms in factored form as

9×3 + 9×5

Now, since 9 is in both the factors. Hence, we can factored out 9

Factored out 9, we get

9 (3 + 5)

Therefore, the equivalent expression for 27 + 45 is 9 (3 + 5)

Answer:

9 (3 + 5) is the answer.

The distance from the owl to the squirrel would be found by using the law of sins/co-sins

Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)

cos(50) = 14 / x

x = 14 / cos50

x = 21.78 feet

The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.

The angle of depression is congruent to your angle of elevation (the squirrel's line of sight. These are opposite angles. You use SOH CAH TOA to find the missing information because this forms a right triangle. SO you are really trying to solve for the hypotenuse here.
You are given the "side" opposite the angle. souse the SOH part Sine=opposite/hypotenuse
so when you plug in the information you get this equation:
sin(50)=14/x
divide both sides by sin(50) and you should get
a hypotenuse of approx. 18.3
