Answer:
Dalton spent 6 years and 11 months in high school.
Step-by-step explanation:
Dalton were in high school at the age = 11 years and 3 months He left high school at the age = 18 years and 2 months
Time spent by Dalton in high school = 18 years 2 months - 11 years and 3 months
= (18 - 11) years and (2 - 3) months
= 7 years - 1 month
= (6 + 1) years - 1 month
= 6 years + 1 year - 1 month
= 6years + 12 months - 1 month
= 6 years + 11 months
Therefore, Dalton spent 6 years and 11 months in high school.
Answer: the area is 84 cm^2
It's $21,000. You multiply $24,000 by 12.5% which is $3,000 then you minus that to 24,000.
(−3y^2−7y−9)−(4y^2+6y+9). To solve this you must:
Distribute the negative sign like this:<span>
=<span><span><span><span>−<span>3y^2</span></span>−7y</span>−9</span>+<span>−1<span>(<span><span><span>4y^2</span>+6y</span>+9</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span><span>−<span>3y^2</span></span>+</span>−7y</span>+</span>−9</span>+<span>−1<span>(<span>4y^2</span>)</span></span></span>+<span>−1<span>(6y)</span></span></span>+<span><span>(−1)</span>(9)</span></span></span><span>
=<span><span><span><span><span><span><span><span><span><span><span>−<span>3y^2</span></span>+</span>−7y</span>+</span>−9</span>+</span>−<span>4y^2</span></span>+</span>−6y</span>+</span>−9
</span></span>Then combine Like Terms:<span>
=<span><span><span><span><span><span>−<span>3y^2</span></span>+<span>−7y</span></span>+−9</span>+<span>−<span>4y^2</span></span></span>+<span>−6y</span></span>+−9</span></span><span>
=<span><span><span>(<span><span>−<span>3y^2</span></span>+<span>−<span>4y^2</span></span></span>)</span>+<span>(<span><span>−7y</span>+<span>−6y</span></span>)</span></span>+<span>(<span>−9+−9</span>)</span></span></span><span>
=<span><span><span>−<span>7y^2</span></span>+<span>−13y</span></span>+−18
</span></span><span>So you would get an answer of </span>−7y^2−13y−18.
Hope this helped!
This triangle would be isosceles since two of the sides have the same length.
