Answer:
q = -4
q = -5/9
Step-by-step explanation:
Hi!
To solve this question, we can use the zero product property.
<h2>What is the Zero-Product property?</h2>
The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.
We have (q+4)(9q +5) = 0
That means either q + 4 = 0, or 9q + 5 = 0.
Solve:
- 9q + 5 = 0
- 9q = -5
- q = -5/9
We can check both cases:
(-4 + 4)(-36 + 5) = 0
0(-31) = 0
0 = 0
(-9/5 + 4)(9(-5/9) + 5) = 0
(2.2)(-5 + 5) = 0
(2.2)0 = 0
0 = 0
Answer:
a) 72 cm2 (centimeter square)
b) 9 cm2 (centimeter square)
c) 9 cm2 (centimeter square)
d) 54 cm2 (centimeter square)
Step-by-step explanation:
a) the area of the rectangle = Base x Height
= 12 x 6
= 72 cm2 (centimeter square)
b) the area of the triangle A = 1/2 x Base x Height
= 1/2 x 3 x 6
= 9 cm2 (centimeter square)
c) the area of the triangle B = 1/2 x Base x Height
= 1/2 x 3 x 6
= 9 cm2 (centimeter square)
d) area of the parallelogram = area of the rectangle - area of triangle A - Area of triangle B
= 72 - 9 - 9
= 54 cm2 (centimeter square)
-12>/5x-9
+9 A Los dos lados
-3>/5x
÷5 Los dos lados
-3/5 >/ x
x </ -3/5
Answer:
17.32%
Step-by-step explanation:
markup = selling price - cost / cost
= 25750 - 21950 / 21950
= 3800 / 21950
= 0.1731207...
17.32%
