(4i)^2+2*4i1+1^2

then simplify

2)remove parentheses

x+1+(x-2)(x+3)

expand (x-2)(x+3)

x+1+x^2+x-6

simplify x+1+x^2-6 = x^2+2x-5

Formula for Compound Interest

Amount = Principal * (1 + Rate/100)^Time
A = P * (1 + R/100)^T
P = A/((1 + R/100)^T) = 92000/((1 + 4.7/100)^16) = $44120.5503

The perimeter of the triangle will be 41ft

<h3>The perimeter of a triangle</h3>

The perimeter of a triangle is the sum of all the sides of the triangle

From the given triangle, we need to get the third sidee firse as shown:

h² = 12² + 12²

h² = 144 + 144

h² = 288

h = 17ft

Perimeter = 12 + 12 + 17

Perimeter = 41ft

Hence the perimeter of the triangle will be 41ft

Find the value of x. Round the length to the nearest tenth.

STALIN [3.7K]

Answer:

x = 5.13 yards to the nearest tenth

Step-by-step explanation:

The diagram is redrawn and labelled in the attached photo.

It is labelled as triangle ABC. Angle A is determined to be 25 degrees. This is because it is alternate to 25 degrees at the top.

To find x, we will apply trigonometric ratio

Tan # =opposite side / adjacent side

Where # = 25 degrees

Opposite side = x

Adjacent side = 11

Tan 25 = x/11

x = 11tan25

x = 11× 0.4663

x = 5.1293 yards

x = 5.13 yards to the nearest tenth.
