(x+1) x (3x-4) is the answer
Answer:
A. 7.5 cm
Step-by-step explanation:
3/4 = (x + 3)/(2x + 1)
3(2x + 1) = 4(x + 3)
6x + 3 = 4x + 12
2x = 9
x = 4.5
BC = x + 3
= 4.5 + 3
= 7.5 cm
<span>All triangles use the same formula for area:
1/2 * B * H</span>
x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
