Hope this helps!
Hi there
-(-2a+13)+(-9-2)-(-7a-3)
-(-2a+13)-9a-2-(-7a-3)
Distribute the negative sign
-(-2a+13)-9a-2+-1(-7a-3)
-(-2a+13)+-9a+-2+-1(-7a)+(-1)(-3)
-(-2a+13)+-9a+-2+7a+3
Distribute
2a+-13+-9a+-2+7a+3
Combine like terms
2a+-13+-9a+-2+7a+3
(2a+-9a+7a)+(-13+-2+3)
=-12
Any questions ?
I hope that's help !
Answer:

Step-by-step explanation:
Answer:
£495 million
Step-by-step explanation:
To find out the total cost of the land, we need to first calculate the area of the land.
Step 1: Find area of right angled triangle ADC
AD = 5 km,
DC = 12 km
Area of the right triangle = ½*a*b
a = 5km
b = 12km
Area = ½*5*12
= 5*6
Area of ADC = 30 km²
Step 2: Find the area of triangle ABC
First, let's find the length of AC using Pythagorean theorem
AC² = AD² + DC²
AC² = 5² + 12² = 25 + 144
AC = √169
AC = 13km
Area of ∆ABC = ½*AB*AC*sin(30°)
= ½*6*13*0.5
= 3*13*0.5
Area of ∆ABC = 19.5 km²
Total area of the land = area of ∆ADC + ∆ABC = 30 + 19.5 = 49.5 km²
Step 3: calculate how much the land costs
If the land costs £10 million per km²,
Cost of 49.5 km² = 49.5 × 10 = £495 million
