Answer:
970m^{2}
Step-by-step explanation:
This polygon can be divided in two figures: one is a triangle, an the other one is a square.
We'll begin calculating the triangle's area, using the following formula:
Where:
As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.
Now we are going to calculate the square's area, that is much more simple:
Where:
To know the whole figure's area, we add up both areas:
Answer:
289 meters I believe.

Answer:
C, x^3+x^2−7x−15
Step-by-step explanation:
=(x+−3)(x^2+4x+5)
=(x)(x^2)+(x)(4x)+(x)(5)+(−3)(x^2)+(−3)(4x)+(−3)(5)
=x^3+4x^2+5x−3x^2−12x−15
=x^3+x^2−7x−15
Answer:
I don't have c but I do have a and b
Step-by-step explanation:
Part A)
Angle 3 is 103° because 77° + ∠3= 180° and ∠3 = 180° - 77° = 103°
Part B)
Angle 4 is 77° because ∠3 + ∠4 = 180° and ∠4 = 180° - 103° = 77°

Answer:
Faith made = x = 24 cookies
Trinity made = y = 64 cookies
Step-by-step explanation:
Faith and Trinity are making cookies for Valentines day. Together they make a total of 88 cookies. How many cookies did each girl make?
Let the number of cookies
Faith made = x
Trinity made = y
x + y = 88
Trinity makes 40 cookies more than Faith.
y = x + 40
We substitute
x + y = 88
x + x + 40 = 88
2x + 40 = 88
2x = 88 - 40
2x = 48
x = 48/2
x = 24 cookies
y = x + 40
y = 24 + 40
y = 64 cookies
Therefore:
Faith made = x = 24 cookies
Trinity made = y = 64 cookies
