Answer:

4±√5

EXPLAINED ANSWER:

Since the variable is a binomial and it is squared, we apply square root on both side, and apply the ± sign on the right side (since the solution of a square root can be both positive and negative), and later pass the 4 positive to the other side.

√25 can be (5)(5) or (-5)(-5)

Tomas and Tasha were hiking at a speed of 3.5 mph. On their way back, they were tired and their speed was 2 mph. How long was th

Anna35 [415]

To get the length of the route use the expression for speed,

Distance = Speed × Time

Length of the route is 7 miles.

It's given in the question,

Speed of Tomas and Tasha initially = 3.5 mph

Therefore, distance travelled by both with the speed of 2 mph one way will be,

Distance = 3.5t [Here, t = time ]

Speed of both while coming back = 2 mph

And the time taken = t + (1 hour 30 minutes)

= (t + 1.5) hours

Therefore, distance travelled while coming back = Speed × Time

= 2(t + 1.5)

Since, length of the route is same both ways,

3.5t = 2(t + 1.5)

3.5t = 2t + 3

3.5t - 2t = 3

1.5t = 3

t = 2 hours

Now substitute the value of t in the expression to get the distance of the route,

Distance = 3.5t

= 3.5 × 2

= 7 miles

Therefore, route was 7 miles long.

Solve y = f(x) = (2x+1)^1/2 & g(x) = x-1

snow_lady [41]

Answer:

f(x) = $x = \frac{y^{2} - 1}{2}$

g(x) = 1

Step-by-step explanation:

y = (2x + 1)^1/2

$y^{2} = 2x + 1$

$y^{2} - 1 = 2x$

$\frac{y^{2} - 1}{2} = x$

y = x - 1

y + 1 = x

What is the area of figure ABCD?

klasskru [66]

Answer: 120

Step-by-step explanation: We can solve this by finding the area of the right triangle and the area of the rectengle and adding both of them. To find the area of the rectengle we use the formula base times height or (b)(h). The base is 13 and the height is 8 so it turns to 8 times 13 which equalls 104. We then need to find the area of the traingle. The formula for that is one half times base times heigt of (1/2)(b)(h). The height of the traingle is the same as the height of the rectengle which is 8 inches. The base of the rectangle is 13 and the base of the rectangle plus the base of the traiangle is 17. To find the base of the traingle we do 17-13 which equalls 4. We then input these numbers into the equation (1/2)(b)(h) which is (1/2)(8)(4) which equals 16. The area of the rectangle (104 inches) plus the area of thetriangle (16 inches) equal 120.

"Proportionality Theorem" compares the sides of the same triangle
Here, According to that theorem,
ST / RS = UT / PU

If FG is an altitude, then <DFG is an right triangle.
In short, Your Answer would be Option B

For last question here, remember, longest side must be greater than either side, and must be smaller than sum of those smaller sides.
