Answer: See explanation
Step-by-step explanation:
Let the width be x
Then, the length will be x+4
Area = Length × Width
Therefore,
x × (x+4) = 60
x² + 4x = 60
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0
x = 6
The width is 6feet
Length = 6+4 = 10 feet

Add parentheses to make true 36 / 9 - 3 = 6
36/ (9 - 3) = 6
Cause:
9 - 3 = 6
Then:
36/6 simplified equals 6
So, your answer is 36/(9 - 3) = 6
Hope it helps! Good luck friend! :3
Answer:
36 / (9 - 3) = 6
Step-by-step explanation:
If you put the parentheses around 9 - 3, that will give you 6. 36 divided by 6 = 6. Also, in PEMDAS, Parentheses comes first, so that is why the parentheses go there to make this true.

Anyone can help me with math for solving for a side in the right triangles for khan academy
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

Divide using synthetic division (x^2 +9)÷(x-3) =
Answer: x+3+ 18/x-3
Step-by-step explanation:
The complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
To divide using synthetic division, we follow these steps:
Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.
Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.
Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.
Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.
Repeat this process until you have found the coefficients of all the terms in the quotient.
Using this process, we can divide (x² +9) by (x-3) as follows:
The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)
