A carpenter added a diagonal brace to gate. The gate is 8ft. Wide and 10 ft. Tall. How long is the brace

Answers

Answer:

The brace is 2√(41) ft ≅ 12.806 ft long

Step-by-step explanation:

The length of the diagonal of a rectangle can be found using this rule

d=\sqrt{l^(2)+w^(2)} , where

  • l is its length
  • w is its width

∵ The gate has shaped a rectangle

∵ Its length = 10 ft

∵ Its width = 8 ft

∴ l = 10 and w = 8

∵ The brace is the diagonal

→ By using the rule above

∴ d=\sqrt{(10)^(2)+(8)^(2)}=√(100+64)=√(164)

∴ The length of the brace = 2√(41) ≅ 12.806 ft

∴ The brace is 2√(41) ≅12.806 ft long

What value or values of x satisfy 2|x + 5.3| = 4.2? x can only equal –3.2. x can only equal 7.4. x can equal –3.2 or –7.4. x can equal –3.2 or 7.4.

Answers

2 | x + 5.3 | = 4.2
| x + 5.3 | = 4.2 / 2
| x + 5.3 | = 2.1

x + 5.3 = 2.1              x + 5.3 = - 2.1
x = 2.1 - 5.3               x = -2.1 - 5.3
x = - 3.2                     x = - 7.4

solution is : x = -3.2 or x = -7.4

Answer:

What value or values of x satisfy 2|x + 5.3| = 4.2?

x can only equal 7.4.

x can equal –3.2 or –7.4.

x can equal –3.2 or 7.4.

Step-by-step explanation:

x can equal –3.2 or –7.4. Is the correct answer.
