I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:
-c^2-4c+21
From here, we’ll factor out a -1 so that we have:
-(c^2+4c-21)
Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:
(c + (-3))(c + 7)
(c - 3)(c + 7)
And adding back on the negative from a few steps earlier:
-(c - 3)(c + 7)
1/3 of 5/8...." of " means multiply
1/3 * 5/8 = 5/24 lbs
Answer:
Step-by-step explanation:
Without brackets, we are not exactly sure what is under the root sign. There are 3 choices.
sqrt(x) + 2 - 15 = - 3
sqrt(x + 2) - 15 = - 3
sqrt(x + 2 - 15) = - 3
I think the middle one is what you intend. If not leave a note.
sqrt(x + 2) - 15 = - 3 Add 15 to both sides.
sqrt(x + 2) - 15+15 = - 3+15 Combine
sqrt(x + 2) = 12 Square both sides
x + 2 = 12^2 Do the right
x + 2 = 144 Subtract 2 from both sides.
x + 2-2 = 144-2
x = 142

Answer:
Option C is correct.
Environmental regulation has led to dramatic improvements in air and water quality.
Step-by-step explanation:
- The national forests are protected from the exploitive ""dual use policy.
The dual use policy on any idea, technology, breakthrough etc. means such concept can be used for its intended purpose and for military use.
Natural forests are not excluded from this dual use policy & plenty forest exploiters hide under this policy to literally exploit natural forests.
- The Environmental Protection Agency was elevated to cabinet status in 1998 by President Clinton and the Republican Congress
This is not true as the EPA is still not a Cabinet department, but the Administrator is normally given cabinet rank.
- Environmental regulation has led to dramatic improvements in air and water quality.
Regulations have led plenty industries at the forefront of pollution to sit up and fix up. Strict laws and hefty fines have discouraged various water and air pollution means since those regulations came into place. This is the only correct statement about environmental policy amongst the options.
- Policymakers always give more consideration to environmental protection than to economic development when the two conflict.
This is true sometimes, but 'always'!? No, policymakers do not always give more consideration to environmental protection than to economic development when the two conflict.
