Answer:
3x^2 + 2x - 3y - 10
Step-by-step explanation:
7y + 2x - 10y +3x^2 - 10x
I like to put it in order starting with exponents like this
3x^2 + 2x - 10x + 7y - 10y
then combine like terms
3x^2 - 8x - 3y
that is as simplified as it gets.
Answer:
32.625 m
Step-by-step explanation:
You have the proportion ...
18 cm : ___ m = 22.4 cm : 40.6 m
This can be rearranged to ...
___ m/(18 cm) = (40.6 m)/(22.4 cm)
Multiplying by 18 cm gives ...
___ m = (40.6 m)·(18/22.4)
___ m = 32.625 m
Answer:
56.9
Step-by-step explanation:
cos y = 6/11
y = cos‐¹ (6/11)
= 56.9
hope it helps!
30 + 4x + 2 + 180 - (8 + 6x) = 180;The sum of all angles in a triangle is 180
32 + 4x - 8 - 6x = 0
2x = 24
x = 12
Bolded part, explanation: On a straight line, the sum of all angles is 180 degrees. We have the value of outside the triangle, the exterior angle, which, when is added with interior angle, gives 180 degrees. So we substract 8 + 6x from 180, that's the third angle in a triangle.
Answer:
The volume of a prism=Bh
We have base area=44
Hieght=5
Thus V= 44*5
V=220
Thus the volume is 220cm³
