Answer:
<h2>The length of the pieces is 3 inch, 6 inch and 13 inch.</h2>
Step-by-step explanation:
Let, the length of the first piece is x inch.
Hence, the length of the second piece is 2x.
It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.
The total length of the steel is 22 inch.
Hence, x + 2x + 4x + 1 = 22
or, 7x = 21
or, x = 3.
The length of the second piece is 6 inch.
The length of the third piece is 13 inch.
Hi! The equation to this problem is:
b/2 ≥ -16
Here are the steps to solving it:
b/2 * 2 ≥ -16 * 2
b ≥ -32
Hope this helps you!

Answer: the length of the other side is 16.5 units.
Step-by-step explanation:
The rectangle has 2 equal and parallel sides. Each of the 4 angles in a rectangle is 90°. This means that the diagonal of the rectangle divides it into 2 equal right angle triangles and the diagonal represents the hypotenuse of both right triangles.
To determine the length of the other side, x, we would apply Pythagoras theorem. It is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
17² = x² + 4²
289 = x² + 16
x² = 289 - 16 = 273
x = √273
x = 16.5 units
Answer:
correct / incorrect / incorrect
Step-by-step explanation:
5a - 8 + 2a² + 2a - 1 ← collect like terms
= 2a² + 7a - 9 ← correct
-------------------------------------
b² + 6b - 4 - (3b + b²) ← distribute parenthesis by - 1
= b² + 6b - 4 - 3b - b² ← collect like terms
= 3b - 4 ≠ 2b² + 3b - 4
---------------------------------------
9c - 4c² - (2c² + c) ← distribute parenthesis by - 1
= 9c - 4c² - 2c² - c ← collect like terms
= - 6c² + 8c ≠ - 6c² + 10c
