Answer:
5
Step-by-step explanation:
[3(5 + 6) + 2] ÷ 7
(5 + 6) = 11
[3(11) + 2] ÷ 7
3 x 11 = 33
[33 + 2] = 35
[35] ÷ 7 = 5
Thus the answer, 5
Answer:
h=9cm
P=(x+5)cm
b=(x-3)cm
by the Pythagoras theorem,
h^2=p^2+b^2
9^2=(x+5)^2+(x-3)^2
81=x^2+10x+25+x^2-6x+9
81=2x^2+4x+34
y=2/3x-3
y=-3/2x+2
Answer:
Step-by-step explanation:
3y = 2x - 9
2y = -3x + 4
3x + 2y = 4
-2x + 3y = -9
6x + 6y = 8
-6x + 9y = -27
15y = -15
y = -1
3(-1) = 2x - 9
-3 = 2x - 9
6 = 2x
3 = x
(3, -1)
