Step-by-step explanation:
The expressions are equivalent by the distributive property.
Answer:
-3
Step-by-step explanation:
Let n be the number
product of seven and a number
7n
is negative 21

<u>Isosceles trapezoid</u>
- ∠R and ∠S are supplementary
- ∠S≅∠T, ∠R≅∠V
- m∠S = m∠T = 54°
- m∠R = 180° - 54° = 126°
(9)
<u>Midsegment is half the sum of the base lengths</u>
- ST = 1/2(FP + EQ)
- 3.1 = 1/2(2.7 + EQ)
- 2.7 + EQ = 6.2
- EQ = 6.2 - 2.7
- EQ = 3.5
For this case we must solve the following quadratic equation:
We must apply the following formula:
We have to:
Substituting we have:
Thus, the solutions are:
