A) 9 + 3x + 6 + 9x + 5
b) 12x + 20
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab +b²
a = y & b = 10
(y + 10)² = y² + 2 *y*10 + (10)²
= y² + 20y + 100
Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)
I cannot guarantee this is correct but hope it helped
The expression equivalent to given expression is 
<em><u>Solution:</u></em>
Given expression is:
We are asked to find the expression equivalent to given expression
Assume that denominator does not equal to zero
We can apply the exponent rule in given expression
Apply the above rule in given expression
Thus the equivalent expression is found
180 N
Step by Step Explanation :
Step 1 :
Given that the buoyant force of the boat is 260 N
and the boat's weight is 80 N
We have to find the maximum weight capacity of the boat so that it continues to float.
The boat would float when the total of the weight of boat and the load it carries do not exceed the buoyant force.
Step 2 :
The weight capacity of the boat is therefore 260 N - 80 N = 180 N
Hence the boat can carry a weight of 180 N to continue to float
