Answer:
√30-√18+√55-√33/2
Step-by-step explanation:
What is the following quotient? sqrt6+sqrt11/sqrt5+sqrt3
Given the expression
√6+√11/√5+√3
Rationalize
√6+√11/√5+√3 × √5-√3/√5-√3
= √30-√18+√55-√33/√25-√9
= √30-√18+√55-√33 /5-3
= √30-√18+√55-√33/2
This gives the required quotient
Answer:
530.66 cm squared
Step-by-step explanation:
c = 2(3.14)r
81.64 = 2(3.14)r
Divide both sides by 6.28
The radius is 13
a = 3.14(13 squared)
a = 530.66
Answer:
1
Step-by-step explanation:
There can be 0, 1 or infinitely many solutions. 0 if they are parallel and are different lines, 1 if the slopes are different, and infinitely many if they are the same line.
2x - 4y = 8
x + y = 7
Change to y = mx + b
y = (1/2)x - 2
y = -x + 7
The slopes are different so there is 1 solution.

B. 12
Ex: 12 squared is 144
Answer:
-80
Step-by-step explanation:
→ Complete the multiplication
20 × 8 = 160
→ Complete the take away
3 - 5 = -2
→ Divide the two answers from each other
160 ÷ -2 = -80
