Answer:

x + 5

Step-by-step explanation:

  • 4x + 8 + (-3)(x) + (-3)(1)
  • 4x + 8 -3x -3
  • (4x-3x) + (8-3)
  • x + 5

Therefore, the answer is x + 5.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

  • x + 5

Step-by-step Solution:

<u>First, we will simplify the distributive property, then we will simplify and obtain our result.</u>

  • (4x + 8) - 3(x + 1)
  • => 4x + 8 - 3x - 3
  • => x + 8 - 3
  • => x + 5

Hence, the simplified expression is x + 5.

A right rectangular prism is shown. The two dimensional net is also shown. Find the surface area of this prism.
Natasha_Volkova [10]

Hey!

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

Surface Area Formula: 2LW * 2LH * 2WH

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

2LW:

5 x 1 = 5

5 x 2 = 10

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

2LH:

4 x 1 = 4

4 x 2 = 8

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

2WH:

5 x 4 = 20

20 x 2 = 40

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

Surface Area:

40 + 8 + 10= 58

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

Answer:

D) 58 cm2

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

Hope This Helped! Good Luck!

A. Work of 5 Joules is done in stretching a spring from its natural length to 16 cm beyond its natural length. What is the force
kirza4 [7]

Answer:

(a) 62.5 N

(b) 694.4 N/m

(c) 41.7 N

Step-by-step explanation:

Work done in stretching a spring is

W = \frac{1}{2}Fe=\frac{1}{2}ke^2 since F=ke

F is the applied force, E is the elongation and k is the spring constant.

(a) Here, e = 16 cm = 0.16 m

W = \frac{1}{2}Fe

F = \dfrac{2W}{e} = \dfrac{2\times5}{0.16}=62.5\text{ N}

(b) Here, e = 12 cm = 0.12 m

W =\frac{1}{2}ke^2

k=\dfrac{2W}{e^2}=\dfrac{2\times5}{0.12^2}=694.4\text{ N/m}

(c) The restoring force is the same as the applied force.

F = \dfrac{2W}{e} = \dfrac{2\times5}{0.12}=41.7\text{ N}
