Well, it is 3 polynomials so let’s break it down first.
(-3x*2 -2xy +y*2) (-4x*2 -xy + 6y*2)
Let’s add these first. The rule is to drop parentheses and add regularly. Bases stay the same, powers add and coefficients multiply.
Ans: (-7x*4 -3x*2 y*2 + 7y*4)
Now let’s add it with the last one.
The answer is: -6x*6 +3x*3 y*3 -6y*6
Answer:
B
Step-by-step explanation:
2x-5y=-25
5y=2x+25
y=2/5 x+5
By using distance formula (which is attached below), you can solve this problem:
√(x2-x1)^2+(y2-y1)^2
(5, -1) and (5, 3)
√(5-5)^2+(3-(-1))^2
√0^2+4^2
√0+16
√16
4
The distance between the two points is 4.
Answer:
57°
Step-by-step explanation:
The sum of both angles is 90°
3x+5x+2=90
8x+2=90
8x=88
x=11
Plug x into the equation
Larger Angle
5(11)+2=57
Smaller Angle
3(11)=33
Answer: 10/63
Step-by-step explanation: To multiply fractions, you just time's the top numbers and then the bottom numbers by themselves.
For instance: 2 x 5 = 10
9 x 7 = 63
and there is your answer.
