x = 37.5 (or)
Solution:
Given .
Let us take BE = x and BC = 25 + x.
To determine the value of x:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Do cross multiplication, we get
Subtract 30x from both sides of the equation.
Divide by 20 on both sides of the equation, we get
x = 37.5 (or)
Hence the value of x is 37.5 or .
Answer:
y² + bs²y - 6b²s⁴
General Formulas and Concepts:
- Expand by FOIL (First Outside Inside Last)
- Exponent Power Rule:
Step-by-step explanation:
<u>Step 1: Define expression</u>
(y - 2bs²)(y + 3bs²)
<u>Step 2: FOIL</u>
- First: y · y = y²
- Outside: y · 3bs² = 3bs²y
- Inside: -2bs² · y = -2bs²y
- Last: -2bs² · 3bs² = -6b²s⁴
<u>Step 3: Simplify</u>
- Combine: y² + 3bs²y - 2bs²y - 6b²s⁴
- Combine like terms: y² + bs²y - 6b²s⁴
