Answer:
-47b + 19
Step-by-step explanation:
Answer:
<h2>a = 400/21, b = 580/21</h2>
Step-by-step explanation:
Small triangles are similar. Therefore, the sides are proportional
<em>cross multiply</em>
<em>divide both sides by 21</em>

For b, we can use the Pythagorean theorem:

Answer:
12x + 4
Step-by-step explanation:
ok so a rectangle has 4 sides, 2 of which are called lengths, and 2 of which are widths.
length = 2x-3
width = 4x+5
the perimenter is the total of the 4 sides.
2(2x-3) = 4x-6 (the total for lengths)
2(4x+5) = 8x+10 (the total for widths)
add the 2 together:
12x+4
The number 390.0826 in an expanded form is 300 + 90 + 8/100 + 2/1000 + 6/10000
<h3>How to write the number in an expanded form?</h3>
The number is given as:
390.0826
Next, we split the numbers:
This is done as follows:
