Answer:
87
Step-by-step explanation:
Look at it upside down!
Combine like terms
8x+24=x+5
subtract x from both sides
8x+24=x+5
-x -x
7x+24=5
subtract 24 from both sides
7x+24=5
-24 -24
7x = -19
divide 7 from both sides
7x = -19
7x/7 = -19/7
x= -19/7
Answer:
144.44%
Step-by-step explanation:
780/540 = 1.44444 * 100 (for each percent) = 144.44 %
A = (H * B) / 2.......2A = H * B
A = 15
H = B + 1
2(15) = H * B
30 = B(B + 1)
30 = B^2 + B
B^2 + B - 30 = 0
(B + 6)(B - 5) = 0
B + 6 = 0
B = -6.....not this one, it cant be negative
B - 5 = 0
B = 5 <==== base is 5 cm
H = B + 1
H = 5 + 1
H = 6 <=== height is 6 cm
