Answer:
10.5
Step-by-step explanation:
<span>4(5x - 20) = -20
Use distributive property
20x-80=-20
Add 80 to both sides
20x=60
Divide 20 on both sides
Final Answer: x=3</span>
I believe the correct answer is false. Quadratic equations that can be solved using the quadratic formula cannot always be solved by factoring. <span>Not </span>all quadratic equations can<span> be </span>solved by factoring<span>. Another method that can be used is completing the square. Hope this answers the question.</span>
Answer:
option A is correct that is 17.
Step-by-step explanation:
We have been given a histogram which is showing y-axis represents number of fundraisers and x-axis represents funds
So, we need to find the number of fundraisers raised funds between $600 and $800
In $600- $800 funds interval the number of fundraisers are 10+7 =17
So, option A is correct that is 17.
Answer:
3. 45, 4. 24
Step-by-step explanation:
use formula: hypotenuse²= side² + other side ²
3.
x²= 27²+36² calculate the squares then add
x²=2025 square root both sides
x= √2025= 45
4.
25²= x²+7² isolate the vaiable by subtracting 7² from both sides
25²-7² = x² square then subtract
576 =x² square root both sides
24=x
