Help? I will give brainliest<br> Find the area of the square if its side is (8x+1) feet.
FrozenT [24]

Answer:

62x^2 + 16x + 1

Step-by-step explanation:

The area of a square is Side times Side.

One of the sides is (8x + 1). So the equation is,

(8x + 1) * (8x + 1)

62x^2 + 16x + 1

6p+4/6=4p-8/3 please show work and explain in full details
Verdich [7]
6p+4/6=4p-8/3 The goal is to always isolate the variable which in this case is p
First bring 4p to the left by subtracting (opposite operation) 4p from both sides. We are left with 2p+4/6=-8/3. We will continue isolating the variable by bring 4/6 to the right by subtracting it from both sides.
We are left with 2p=-10/3
Then divide (opposite operation) both sides by 2 to get p=-5/3

Show that 8^3 − 1 is divisible by 7.
Brilliant_brown [7]

Answer:

8•8=64•8=512-1=511÷7=73

Step-by-step explanation:

8 to the power of 3 is divisible by 7 because if the result is a real number, then you got it correct. We got a whole number here, so it was easier but if you get decimals, it takes more work. Well, there's your answer, hope it helped!!!

Which of the following is the correct point-slope equation for the line that passes through the point (-6, -1) and is parallel t
inn [45]

Answer:

A. y + 1 = 7(x + 6)

Step-by-step explanation:

1) Point slope form is

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line

2) Parallel lines have the same slope

in this case m = 7

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

Plug in m = 7 and (x1, y1) = (-6, -1)

y + 1 = 7(x + 6)

which is answer A
