Answer:

You just need to substitute 4 in for h.

So 48 + 25(4) = 48 + 100 = 148

The width of a rectangle is y feet long. The rectangle is 4 feet longer than it is wide. What is the area of the rectangle?

mario62 [17]

Answer:

if breadth is y feet long

let length be y+4

Step-by-step explanation:

therefore,

area=(4+y)*y

area=4y+y2

An equailateral triangle is also an

Alinara [238K]

Answer:

C) isosceles triangle

Step-by-step explanation:

equilateral triangle has all sides the same and all angles the same

180/3 = 60 so each angle is 60 degrees

A) obtuse triangle

means it has an angle bigger than 90 degrees

B) right triangle

that means it has an angle at 90 degrees

C) isosceles triangle

That means it has 2 sides that are the same

D) scalene triangle

that means it has no sides the same

If it has 3 sides the same. it must have 2 sides the same. So any equilateral triangle must be an isosceles triangle

What is 720° converted to radians? <br> a) 1/4<br> b) pi/4<br> c) 4/pi<br> d) 4pi

baherus [9]

4π radians

<h3>Further explanation</h3>

We provide an angle of 720° that will be instantly converted to radians.

Recognize these:

$\boxed{ \ 1 \ revolution = 360 \ degrees = 2 \pi \ radians \ }$
$\boxed{ \ 0.5 \ revolutions = 180 \ degrees = \pi \ radians \ }$

From the conversion previous we can produce the formula as follows:

$\boxed{\boxed{ \ Radians = degrees \times \bigg( \frac{\pi }{180^0} \bigg) \ }}$
$\boxed{\boxed{ \ Degrees = radians \times \bigg( \frac{180^0}{\pi } \bigg) \ }}$

We can state the following:

Degrees to radians, multiply by $\frac{\pi }{180^0}$
Radians to degrees, multiply by $\frac{180^0}{\pi }$

Given α = 720°. Let us convert this degree to radians.

$\boxed{ \ \alpha = 720^0 \times \frac{\pi }{180^0} \ }$

720° and 180° crossed out. They can be divided by 180°.

$\boxed{ \ \alpha = 4 \times \pi \ }$

Hence, $\boxed{\boxed{ \ 720^0 = 4 \pi \ radians \ }}$

<u>Another example:</u>

Convert $\boxed{ \ \frac{4}{3} \pi \ radians \ }$ to degrees.

$\alpha = \frac{4}{3} \pi \ radians \rightarrow \alpha = \frac{4}{3} \pi \times \frac{180^0}{\pi }$

180° and 3 crossed out. Likewise with π.

Thus, $\boxed{\boxed{ \ \frac{4}{3} \pi \ radians = 240^0 \ }}$
