Answer:
45 square units.
Step-by-step explanation:
Applying the pythagoras theorem:
Base of the bigger triangle = 
= 
= 12 units
Area of a triangle is given by 
× base × height
The area of the bigger triangle is × 12 × 9 = 54 square units.
The area of the smallest triangle is × (12 - 10) × 9 = 9 square units.
The area of the figure( required triangle) is 54 - 9 = 45 square units.
Answer:
b
Step-by-step explanation:
the answer is b
Here, we are required to write a real-world problem that can be represented by the given equation
On the left hand side of the equation, we can say that :
The addition of 6 to twice my cousin's age which gives 2x+6.
On the right hand side, we can say the addition of 4 to thrice my cousin's age which also gives:
3x +4
Ultimately, the real-world problem may be in the form :
Six added to Twice my cousin's age is equal to 4 added to thrice his age.
Also, my variable, x represents my cousin's age.

Salinas will use 32 gallons for 480 miles
<h3>How to calculate the number of gallons required ? </h3>
Salinas used 15.6 gallons of gas for 234 miles
Miles can be described as the distance travelled by an object or an individual
The first step is to calculate the number of miles travelled using 1 gallon
15.6= 234
1= x
cross multiply both sides
15.6x= 234
x= 234/15.6
x= 15
1 gallon will take her 15 miles
Therefore, the number of gallons required for 480 miles can be calculated as follows
1= 15
x= 480
cross multiply both sides
15x= 480
x= 480/15
x= 32
Hence Salinas will require 32 gallons for 480 miles of the journey
