Answer:
The value of b is 21
Step-by-step explanation:
29=√20^2+b^2
or, 29=√400+b^2
or, 841=400+b^2
or, 841-400=b^2
or, √441=b
b=21
Answer:
what is that suppose to mean
oh wait nvm i get it now im dum
1 hr and 5 mins
srry i didnt know what elapsed meant-
3x^2y^3+5x^3y^3-6+x^3y^2-2
= (3x^2y^3+5x^3y^3+x^3y^2)-(6+2)
= x^2y^2(3y+5xy+x)-8.
The final answer is x^2y^2(3y+5xy+x)-8~
Answer:
x = -7
Step-by-step explanation:
5-x=12
To solve for x, you must first make the equation equal to x (to make x alone on one side).
5 - x = 12
-5 -5
-x = 7
-x(-1)=7(-1)
x = -7
Answer:
<h2><u>
X= 1</u></h2>
Step-by-step explanation:
<em>y = 5 - 3x</em>
<em>5x - 4y = -3</em>
you substitute for y since you know what y equals.
so, it will then be
5x -4(5 -3x) = -3
you then multiply -4 by everything in the parenthesis
so then it will be
5x - 20 + 12x = -3
Then combine like terms
5x + 12x = 17x
then the new equation is
17x -20 = -3
the next step is to and 20 to both sides since it is negative you do the opposite.
17x - 20 = -3
<u> + 20 +20</u>
17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.
<h2><u>
so, X = 1</u></h2>
