(ab + 174)/3 <115
multiply by 3 on each side
ab + 174 < 345
subtract 174 from each side
ab < 171
248+ ab >366
subtract 248 from each side
ab> 118
Answer 118< ab < 171
Ii would have to go with 25m to the second power so b
Answer:
40/3
Step-by-step explanation:
w = weight of soil needed
f = number of flower beds
a = constant value
w = a * f
<em>substitute</em>
10 = 6a
<em>simplify</em>
5/3 = a
w = (5/3)f
<em>plug in 8</em>
w = (5/3)(8)
<em>simplify</em>
w = 40/3
Y = 3 because in a rectangle, the diagonals are ALWAYS congruent. so you would have:
5y - 2 = 4y + 1
-4y+2 -4y + 2
y = 3

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to find the missing side.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 5
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 12
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: 5² + x² = 12²
- Isolate <em>x</em> term: x² = 12² - 5²
- Exponents: x² = 144 - 25
- Subtract: x² = 119
- Isolate <em>x</em>: x = √119
