Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24
Answer:
The answer is 21
Step-by-step explanation:
The answer is 21 because...
- <em>It is hard to explain but for step one you need to take the dotted line and the shape above hat and move it underneath the other shape to make a perfect rectangle.</em>
- <em>Step two since the dotted line is our new bottom. It has a length of 7. In this step we multiply 3 times 7 </em>
- <em>Step 3 this is the final step in which 3 times 7 equals 21.</em>
- <em>Hope this helped :)</em>
Delta(Y)/Y = 0.05 -2Delta(u)
=0.05-2(0.05-0.03) = 0.05-0.04 = 0.01 = 1%
So output (GDP) will increase by 1%
Answer:
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
Step-by-step explanation:
convert feet to yard:
1 yard=3 feet so
12 feet=4 yards
10 feet=10/3 yard=3.33333 yard
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
