18 inches
R= 9
D= 9 x 2
D=18
Answer:
w=16
Step-by-step explanation:
i did this one once so i know it's correct if it's wrong my bad.
Our triangle is ABC with ∠C = 90°
1) AB² = BC² + AC² (Pythagorean theorem)
25² = 20² + AC²
AC² = 625 - 400
AC² = 225
AC = 15
2) PΔABC = AB + BC + AC = 25 + 15 + 20 = 60
3) SΔABC = AC * BC * 1/2 = 15 * 20 * 1/2 = 150
Answer: the perimeter is 60 cm and the area is 150 cm² .
I guessing you want us to find out how many pints of red and white paint is used
ok let's start with this
5x+3x=48
simplify
8x=48
divide
x=6
now multiply to find how much paint
5*6=30
30 pint of red paint
3*6=18
18 pints of white paint
<h3><u>Given</u>:</h3>
- A rectangle has a height of 4 and a width of x² + 3x + 2.
<h3><u>To find</u>:</h3>
- The area of the entire rectangle.
<h3><u>Solution</u>:</h3>
Hence, we know that area of rectangle is equals to the product of length and breadth.
Therefore, the area of rectangle is,
Therefore, the answer is 4x² + 12x + 8.
