What is the value of 4x to the third +4x if x is 4

Mathematics
1 answer:
weqwewe [10]3 years ago
5 0
The correct answer of
4{x}^{2}  + 4x
if x=4 is 272.

to solve the equation if x equals 4, you must substitute the x of the 4.
4( {4}^{3} ) + 4(4)
then solve by order of operations.
solve what is inside the parentheses first
4(64) + 4(4)
then do the multiplication of the factors
256 + 16
then the final step, adding, to get the solution of 272

Find the value of x.
Alina [70]

Answer:

This is a right triangle, so we know that:

h² = b' · c'

which is this case can be specificly written as:

BD² = AD · CD

BD² = 7 · 3 = 21

BD = √21

Now that we can also notice that ΔADB is also a right triangle, therefore we can apply the pythagorean theorem:

AD² + BD² = AB²

7² + (√21)² = x²

x²               = 49 + 21 = 70

x                 = √70

Y = 6x + 8 <br> y = –4x – 2
lara31 [8.8K]

Answer:

x= 2

y = 20

Step-by-step explanation:

y = 6x + 8

y = –4x – 2

y = 4 (6x + 8 )

y = 6 (–4x – 2)

y = 24x + 32

y = –24 -12

___________

y = 20

input that back into the equation to find x

20 = 6x + 8

20 - 8 = 6x

12 = 6x

x= 2
