Answer:

Step-by-step explanation:

AC and D are all wrong. The all add or subtract something from 3 which is not going to keep the two sides of the equation equal.

Only B is correct. To get the two sides equal, you need to multiply the powers by the same constant. B does this. The powers and the constant 1/3 * 3 are the same on both sides.

Which point on the number line best represents√57?

Cerrena [4.2K]

Answer:

Step-by-step explanation:

$\sqrt{57} =\sqrt{3 * 19}$

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.

Hope this helps!

Write the equation in point-slope form of the line that passes through (1, 4) and has a slope of 4/3

suter [353]

Answer:

y - 4 = (4/3)(x - 1)

Step-by-step explanation:

point slope form is

y - y1 = m(x - x1)

m is the slope

(x1, y1) is a point on the line

----------------------------

for m = 4/3 and (x1, y1) = (1, 4)

y - 4 = (4/3)(x - 1)

Guys, please help me faster will receive a Brainliest award if you answer my 2 of the math questions with the best given answers

Zolol [24]

Answer:

Question 10.

Length of the side of the square = $\sqrt{441} = 21$

By Pythagoras' Theorem,

Hypotenuse = $\sqrt{21^{2} + 20^{2} }$ (H > 0)

= 29 m

Ans: 29 m

Question 11.

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- $\sqrt{18^{2} - 15^{2} }$ (L > 0)

= 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = $\sqrt{32.050^{2} + 15^{2} }$ (L > 0)

= 35.4 km (3 s.f.)

Ans: 35 km
