Answer: Simplify  \frac{2}{5}x  

5

2

​  

x  to  \frac{2x}{5}  

5

2x

​  

.

\frac{2x}{5}=6

5

2x

​  

=6

2 Multiply both sides by 55.

2x=6\times 5

2x=6×5

3 Simplify  6\times 56×5  to  3030.

2x=30

2x=30

4 Divide both sides by 22.

x=\frac{30}{2}

x=  

2

30

​  

 

5 Simplify  \frac{30}{2}  

2

30

​  

  to  1515.

HELP!!! Which of the following is not a perfect square trinomial? A. 169 – 26y + y2 B. 81 + 18y + y2 C. 64 + 8y + y2 D. 25 + 10y
natita [175]
Let's review the options:
A. 169-26y+y^2 can be factorised into (13-y)(13-y)
B. 81+18y+y^2 can be factorised into (9+y)(9+y)
C. 64+8y+y^2 cannot be factorised into double brackets
D. 25+10y+y^2 can be factorised into (5+y)(5+y)

Therefore your answer is the odd one out, C.

What is the measure of the missing angle?<br> 40<br> 90
Lyrx [107]

Answer:

50°

Step-by-step explanation:

I am assuming that the shape is a right triangle.

All interior angles of a triangle add up to 180°.

x + 40 + 90 = 180\\\rule{150}{0.5}\\x + 130 = 180\\\\x + 130 - 130 = 180 - 130\\\\\boxed{x = 50}

The missing angle should be 50°.

Hope this helps.

Write the equation of a polynomial of degree 3, with zeros 1, 2 and -1 where f(0)=2
ser-zykov [4K]

Answer:

f(x) = x^3 - 2x^2 - x + 2

Step-by-step explanation:

since the zeroes are 1,-1, and 2. we can write the function like

f(x) = (x-1)(x+1)(x-2)

f(x) = (x^2-1)(x-2)

f(x) = x^3 -2x^2 -x +2

and it is true that f(0)=2

Create an expression that simplifies to sin x
Dimas [21]

Answer:

2\cdot \sin 0.5x \cdot \cos 0.5x

Step-by-step explanation:

Here is one example:

2\cdot \sin 0.5x \cdot \cos 0.5x

\sin 0.5x \cdot \cos 0.5x + \cos 0.5x\cdot \sin 0.5x

\sin (0.5x + 0.5x)

\sin x

Hello there! <br><br> Can I get someone help please ? Thanks!
natulia [17]
Since they are right triangles use Pythagorean Theorem.
a^2 + b^2 = c^2 where c is the hypotenuse.

a.  12^2 + b^2 = 13^2
144 + b^2 = 169
subtract 144 from both sides
b^2 = 25
take the square root of both sides
t = 5  This is also know as a Pythagorean Triple 5-12-13

b.  a^2 + 9^2 = 12^2
     a^2 + 81 = 144
subtract 81 from both sides
a^2 = 63
take the square root of both sides
a = √63
a = √(9 * 7)
a = 3√7

c.   6^2 + 9^2 = c^2
    36 + 81 = c^2
117 = c^2
take the square root of each side
c = √117
c = √(9*13)
x = 3√13
