I really don't how to explain this
Answer:
Ella ran 7.5 meters in 5 seconds
Step-by-step explanation:
d=1.5t
d=1.5(5)
d=7.5
B=2h-7
Area of a triangle: A=1/2 of bh
replace b with 2h-7: A=(1/2)(2h-7)h=102 => (2h-7)h=204
2h^2-7h-204=0
factor or use quadratic function to solve
h=12
b=2*-7=17
Simple, to make it less harder change 4/5 into 0.8
Making the equation,
0.8(15x-5)
Then just multiply:
take 0.8*15(x)=12x
then
0.8*-5=-4
Making the problem, simplified out, 12x-4.
Answer:
her equation should be a² + 3² = 4²
Step-by-step explanation:
a² + 3² = 4²
a² + 9 = 16
a² = 7
a = ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
a ≈ 2.6 inches
