step 1
(x - 4) • (x + 5) = 0
STEP
:
A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
Solving a Single Variable Equation:
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
Solving a Single Variable Equation:
2.3 Solve : x+5 = 0
Subtract 5 from both sides of the equation :
x = -5

Answer:
B. 76°
Step-by-step explanation:
The triangles are congruent (HL), so each has the same angle at vertex C.
2 × 38° = 76°
Angle PCR is 76°.
Pretty good, How about you
We are given : Giannina's painting sold for over $300.
Let the price of Geannina's painting in dollars = P.
<em>Note: We are given a word " over " in above statement.</em>
Over word represents more than. So, we need to use more than inequality symbol to write an inequality for the given statement.
Let us rephrase the given statement.
" Price P is greater than $300".
Now, we can write an inequality :
P> 300.
<h3>Therefore, the required inequality for given statement is P > 300.</h3>
