124 inches of a frame is the required amount. 31 times 4 is 124.

Since it is a square we can use the rules for a 45-45-90 right triangle or Pythagorean Theorem to solve.
Using 45-45-90 rules:
When you cut the square down the diagonal you create a 45-45-90 right triangle with the hypotenuse = 44 in.
The rule is: hyp = sqrt2 * leg
                    44 = sqrt2 * leg
Divide both sides by the square root of 2 to find the leg.
                     31 = leg
To find the perimeter of the square, the length needed to make a frame, multiply the length of the leg by 4.
31 * 4 = 124 in

Solve the inequality 16 > -2u
Ksju [112]
To solve this inequality, you need to isolate the value of u. To do this, divide both sides by -2. When you do this, keep in mind that when you divide or multiply both sides by a negative in an inequality, you MUST flip the sign, so your answer would be -8 < u or u > -8.

Which symbol makes the following TRUE?
olchik [2.2K]

Option A:

6 – 4(3) < 5 – 10

Solution:

Given expression is 6 – 4(3) ____ 5 – 10.

Let us first simplify the expression.

Take left side expression.

⇒ 6 – 4(3)

⇒ 6 – 12

⇒ –6

Take right side expression.

⇒ 5 – 10

⇒ –5

To find which symbol makes the expression true.

In negative the highest number is the lowest in value.

–6 < –5

⇒ 6 – 4(3) < 5 – 10

Option A is the correct answer.

Hence 6 – 4(3) < 5 – 10.
