1.Ms. Pearson assigned her students a section to read on ecosystems in their science book. When finished, she tries to lead an exercise where the children must apply what they have learned. However, no one is participating. This makes no sense to Ms. Pearson because no one gave any indication there was an issue with the text. When asked if they understood the passage, most students confess that they did not. What should Ms. Pearson have done differently?

Group Studies

Explanation:

Ms Pearson as a professional teacher should have group the students into smaller groups,appoint someone to lead the group and emphasize the need for coolaboration in learningbefore proceeding to lead the exercise.

This would have help to create an opportinity for those who understood the section to guide those who did not understand the topic. Again, it would have become an opportunity for them to collaborate as a team, study as a group and address the questions efectively.

Ms Pearson should employ Hands on learning technique

Explanation:

Ecosystems is science and teaching science entails critical thinking, effectual communication, creativity and collaboration. Everything is connected, from the birds of the air, crawling and flying insects, fish and aquatic life, the waste in our environment, trees and forestry , our pets, our food, and ourselves. The following techniques and activities can be employed by Ms Pearson.

Other techniques that can be adopted include story telling where Ms Pearson paints a scenario of a farmer who kills all the lions in the area to protect his livestock. The students are to give their views about the effect of the farmer's action on the ecosystem. Science text cards can also be used to help the students memorize.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
