You treat this problem as though it's a regular triangle.
You plug the numbers 24 and 45 into the equation for a triangle which is A=1/2 (L x W)
So what you get is A= 1/2 (24 x 45)
Which can be simplified to A= 12 x 45.
In the end that totals to 540 meters.

The First One Answer is
x•(1+xy+x^2y)
Answer:
B -1/9
Step-by-step explanation:
(y - 1) / y = 10
y - 1 = 10y
- 1 = 9y
y = -1/9
G(x) = 2x² - 5x + 2 = 2x² - 4x - x + 2 = 2x · x - 2x · 2 - 1 · x - 1 · (-2)
= 2x(x - 2) -1(x - 2) = (x - 2)(2x - 1)
g(x) = 0 ⇔ (x - 2)(2x - 1) = 0 ⇔ x - 2 = 0 or 2x - 1 = 0
x = 2 or x = 0.5
Collect like terms
so take it in steps :
1) -4x^3 * x^-8 . rules of powers state that when you are multiplying like terms(both have to do with x) you can add the powers. thus = -4x^-5
2) 2y^-2 * 5y^5 . same rule as above. since -2+5=3. the number before your coefficient (x or y) tells you how many lots of it you have . the answer becomes 2*5y^3 = 10y^3 .
3) since you are now left with x and y s which are not the same number, you can multiply out ---> 10*-4 = -40
---> y^3*x^-5 stays the same as you can not combine y and x
In total you have : -40y^3*x^-5
