The answer is x=-4 the work is shown on the pic
Answer:
1;no
2; i don^t know
3;c
4;12
5:20
Step-by-step explanation:
reasons
1:sum of all side of triangle is 180 degree(here is 220)
3: try in copy and u will able to solve
4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.
5: 3y+5y+y=180
9y=180
hence,y=20
Larger Number: L
Smaller Number: L-9
Larger Number + Smaller Number = 45
L + L - 9 = 45
2L = 54
L = 54/2
L = 27
Smaller Number = L - 9
27 - 9 = 18
Check. .. 27 + 18 = 45. CORRECT!
Larger Number is 27
Smaller Number is 18
-5m^2 = -125
m^2 = 25
m = SquareRoot (25)
m = 5
Equation has real number solution.
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5
