Answer:
3.69 hours
Step-by-step explanation:
y = 80.25x + 78.75
y = 95.75 + 40
85.25x + 78.75 = 95.75 + 40
-85.25x -40 -85.25x -40
38.75/10.5 = 10.5x/10.5
3.690476190..... = x
rounding
3.69 = x
Answer:
Step-by-step explanation:
Hypotenuse² =base² + altitude²
(3x + 4)² = (2x + 1)² + (3x)²
{Use (a+b)² = a² + 2ab + b²}
(3x)² + 2*3x+4 + 4² = (2x)² + 2*2x*1 + 1² + 9x²
9x² + 24x + 16 = 4x² + 4x + 1 + 9x²
9x² + 24x + 16 = 13x² + 4x + 1
0 = 13x² + 4x + 1 - 9x² - 24x - 16
13x² - 9x² + 4x - 24x +1 - 16 = 0
4x² - 20x - 15 = 0
a = 4 ; b =-20 ; c = -15
D = b² - 4ac = (-20)² - 4*4*(-15) = 400 + 240 = 640
√D = √640 = 25.30

x = 5 .66 ; x = -0.66
Ignore x = -0.66 as length of a side cannot be negative
Answer : x = 5.66
Answer:
so, lauren isn't correct
Step-by-step explanation:
3x + 4 (2x + 5) = 6x + 5x + 5
3x + 8x + 20 = 11x + 5
11x + 20 ≠ 11x + 5
answer:
9/4
step-by-step explanation:
2 as a fraction is 8/4
seeing as how 9/4>8/4
or you could convert 9/4 to a decimal which is 2.25 and 2.25>2
the larger number is 9/4
good luck :)
hopefully, this helps
have a good day !!
