By applying Cathetus theorem, the value of x is equal to 10 units.
<h3>How to determine the value of x?</h3>
In order to determine the value of x, we would apply Cathetus theorem (leg rule), which states that each leg of a right-angled triangle is the geometric mean that's directly proportional between the hypotenuse and the part of the hypotenuse that's directly below the leg.
In this context, we have:
x² = m × a
x² = (21 + 4) × 4
x² = 25 × 4
x² = 100
x = √100
x = 10 units.

Answer:
-8 or -1
Step-by-step explanation:
x*2+9x+8=0
(x+8)(x+1)=0
x+8=0 or x+1=0
x= -8 or x= -1
Answer:
12.50 - 3.75 = 8.75
$8.75 / $1.25 * (1/2) (per mile) = 3.5 miles
1. Mile .5 (fee and 1st mile)
$3.75 + $1.25 = $5.00
2. Miles .5 - 3.5 (additional 3 miles)
$1.25 * (3*2) = $7.50
Total: $5.00 + 7.50 = $12.50
Step-by-step explanation:
85/100
17/20 when simplified
2 3/8 - 1 7/8
Change to improper fractions
19/8 - 15/8 = 4/8 = 1/2
