Answer:

D. 12, 15, 25

Step-by-step explanation:

The triangle leg rule states that the smaller two lengths must add up to be greater than the largest length.

This means that the first two values must add up to be greater than the final value.

12 + 15 = 27

27 > 25

So, your answer is D

Solve –16t² +144= 0 to find the number of seconds, t, it takes for an object dropped from 144 ft above the ground to hit the gro
Vlad1618 [11]

Answer:

h(t) = -16t2 + 144

h(1) = -16(12) + 144 = 128 ft

h(2) = -16(22) + 144 = 80 ft

h(2) - h(1) = 80 - 128 = -48 ft

It fell 48 ft between t = 1 and t = 2 seconds.

It reaches the ground when h(t) = 0

0 = -16t2 + 144

t = √(144/16) s = 3s

It reaches the ground 3s after being dropped.

11111nata11111 [884]

Answer:

DF^2=DH^2+HF^2

DF=√DH^2+HF^2

DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}

DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}

DF=√2*121

DF=√242

DF=15.555

Solve for x.<br> -(12x-6)=12x+6
AfilCa [17]

-(12x - 6) = 12x + 6


First, distribute the negative sign on the left side.

It is the same as multiplying the quantity in parentheses by -1.


-1(12x - 6) = 12x + 6


-12x + 6 = 12x + 6


Now, subtract 12x from both sides.


-24x + 6 = 6


Subtract 6 from both sides.


-24x = 0


Divide both sides by -24.


x = 0/(-24)


x = 0


Answer: x = 0
