23=5-2y
Get y alone,
23-5= 18
18= -2y
Divide to find y
18/-2=-9
Y= -9
Or since you asked for x, X=no solutions.
Hope it helps ❤️
The correct ones are A,B, D&E
The answer to this problem would be 700. if you need the sum that isnt estimated, its 678.
The angles form a right angle, so make an equation where they add up to 90 degrees.
(c + 3) + (4c - 13) = 90
Combine like terms.
5c - 10 = 90
Add 10 to both sides.
5c = 100
Divide both sides by 5.
c = 20
The answer is: [A]: "right [triangle]" .
________________________________________________
Explanation:
________________________________________________
Given: Side lengths:
________________________________________________
" <span>24 in., 32 in., and 40 in " ;
________________________________________________
Divide each side length by "8" ;
</span><span>
24 in. / 8 = 3 in. ;
32 in. / 8 = 4 in. ; and
40 in. / 8 = 5 in. .
_________________________________________________
3 in . , 4, in, 5 in. ; is a "right triangle" ;
since: 3</span>² + 4² = 5² ;
→ 9 + 16 = 25 ;
according to the Pythagorean theorem: " a² + b² = c² " .
