The area is 180ft I think. You can do (15*12)/2 = 90. Since it’s two triangles you then do 90*2. I hope I am right
Answer:
7
Step-by-step explanation:
because 10 x 5 +50 and when u subtract that from 864 there 814 left and 800 can be divided by 10. Therefore 14/ 2 =7 idk if this is right tho
Just did this one.
The perimeter is the sum of the sides.
n + (3n - 4) + (3n - 5) = 33
7n - 9 = 33
7n = 42
n = 6
3n-4=18-4=14
3n-5=13
Check: 6+14+13=33, good
Answer: 6 cm, 14 cm, 13 cm
Hello from MrBillDoesMath!
Answer:
.08%
Discussion:
Let the percent be denoted "p". Then
2000 * p% = 160 => ( as p% = p/100)
2000* p/100 = 160 =>
20p = 160 =>
p = 8 or .08%

Answer: (3x + 4y)(3x + 4y)
Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.
