The answer should be 24 cuz it looks like its adding 6 every time
Answer:
B. 24
Step-by-step explanation:
To find this, use Pythagorean Theorem
a^2+b^2=c^2
a is 10, and c is 26. We know 26 is the hypotenuse because it is opposite the right angle
10^2=b^2=26^2
100+b^2=676
Subtract 100 on both sides
b^2=576
Take the square root of both sides
b=24
Hope this helps! :)
Answer:
(4,10)
Step-by-step explanation:
Input: (3,9)
(3+1, 9+1)
Output: (4,10)
Let the width be called x inches, so the length is x+9 inches (width is 9in shorter than length) and x>0
So the area = w*l = x(x+9)
=> x^2+9x=252
=> x^2+9x-252=0
=> x^2 - 12x + 21x - 252 = 0
=>x(x-12) + 21(x-12) = 0
=> (x-12)(x+21)=0
=> x = 12 or -21
but x>0
=> x = 12 in
=> width = 12 in
=> length = 12+9 = 21 inches
brainliest pls
The answer is: " 12 " .
_____________________________________________
→ " x = 12 " .
_____________________________________________
To solve:
________________________________________________________
3x - 1 = x + 23 ; Solve for "x" ;
Subtract "x" from each side of the equation; & add "1" to each side of the equation;
3x - 1 - x + 1 = x + 23 - x + 1 ;
to get:
2x = 24 ;
Divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
2x/2 = 24/2 ;
to get:
x = 12 .
_____________________________________________
Let us check our answer, by plugging in "12" for "x" ; on EACH side of the original equation; to see if the equation holds true; {that is, to see if each side of the original equation is equal, when "x = 12" } ; as follows:
______________________________________________
3x - 1 = x + 23 ;
Substitute "12" for "x" on each side ;
3(12) - 1 =? (12) + 23 ??
36 - 1 =? 35 ??
35 =? 35?? Yes!
