Answer:
4^2 / px3 = 2/3
Step-by-step explanation:
4^2 / px3 = 4^2 / 8 *3
= 4*4 / 8*3
= 4/ 2*3
= 2/3

Step-by-step explanation:
. You have that:
- The homeowner want the length of the swimming pool to be 4 feet longer than its width.
- He wants to surround it with a concrete walkway 3 feet wide.
- He can only afford 300 square feet of concrete for the walkway.
2. Therefore, the tota area is:
At=L2xW2
L2 is the lenght of the walkway (L2=L1+3+3⇒L2=(W1+4+6)⇒L2=W1+10).
W2 is the width of the walkway (W1+3+3⇒W2=W1+6)
3. The area of the walkway is:
A2=At-A1
A2=300 ft²
4. Therefore, you have that the width of the swimming pool is:
A2=(W1+10)(W1+6)-(W1+4)(W1)
300=(W1²+6W1+10W1+60)-(W1²+4W1)
W1²+16W1+60-W1²-4W1-300=0
12W1-240=0
W1=240/12
W1=20 ft
5. And the length is:
L1=W1+4
L1=20+4
L1=24 ft
Answer:
60
Step-by-step explanation:
You would just plug everything in so you get -5(-2-(-5)(-2)) which can be reduced so -5(-12) which is 60
Answer: A geometric proof involves writing reasoned, logical explanations that use definitions, axioms, postulates, and previously proved theorems to arrive at a conclusion about a geometric statement.
Answer:
Cos(A) = 10/26
Tan(C) = 10/24
Step-by-step explanation:
cos = adjacent/hypotenuse
tan = opposite/adjacent
