Bec 4x-5
Lyrx [107]3 years ago

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees

Which expression shows the sum of the polynomials with like terms grouped together?
Leto [7]

Answer:

C. (-4x^2)+2xy^2+[10x^2y+(-4x^2y)

Step-by-step explanation:

A. [9-4x2) + (-4x2y) + 10x2y] + 2xy2  : in this polynomial the first term is not a like term, then this is incorrect.

B. 10x2y + 2xy2 + [(-4x2) + (-4x2y)]  : in this polynomial, the terms that are grouped, are not like terms, then is incorrect.

C. (-4x2) + 2xy2 + [10x2y + (-4x2y)]  ; This polynomial is the right answer because the like terms are grouped.

D. [10x2y + 2xy2 + (-4x2y)] + (-4x2): This polynomial is incorrect because one of the terms that are grouped is not a like term.

Can you give me equation where x=16
Mashcka [7]
x = 16 in the following equations:
8 × 2 = x
8 + 8 = x
4 × 4 = x

In the following equations, x = 16:
2x = 32
<em>32 ÷ 2 = x = 16
</em>x + 5 = 21
<em>21 - 5 = x = 16</em>
