Answer:
20
Step-by-step explanation:
20 + 20 + 20 = 60 and thats 3
So for this problem, you will need to write out the equation before you can solve the question. The square of two times an integer translates into 2x². In a word problem, "is" means =. Therefore, 2x² is equal to the other half of the equation. To write out the other half of the equation, you have to know that "is more than" means addition. So, 10x+6 is the other half of the equation. your final equation becomes 2x²=10x+6. Then solve the equation like in any other problem: 2x²=10x+6 becomes 2x²-10x-6=0, and then factor or use the quadratic formula.

Answer:
A = 22.5 m²
Step-by-step explanation:
longest side length
b = √((-7 + 4)² + (-1 - 8)²) = √90
other sides
a = √((-1 + 7)² + (2 + 1)²) = √45
height
h = √((√45)² - (½√90)²) = √22.5
Area of triangle
A = ½bh = ½√90√22.5 = 22.5 m²
a little math shows that this triangle is a tilted half of a square with sides √45
Answer:
£ 14,802.32 total investment value.
Step-by-step explanation:
11180 x 0.054^1 = 603.72 interest yr1
603.72 x 6 = 3622.32 interest yr 6
3622.32 + 11180 = 14802.32 = (interest + Initial) = total
