X-the number
6(x + 12) = 40 |use distributive property: a(b + c) = ab + ac
6x + 72 = 40 |subtract 72 from both sides
6x = -32 |divide both sides by 6
x = -32/6
x = -16/3
x = -5 1/3

Answer:
1.5
Step-by-step explanation:
An equation 10(23+7)=100ℓ+100ℓ is given and we are asked to find the value of ℓ.
To solve the equation, we have to move all the values containing ℓ on one side and other values on other side of equality.
10(23+7)=100ℓ+100ℓ
Multiply 10 with 23 and 7 which gives
(10 * 23 ) + ( 10 * 7) = 200 ℓ
Solving the above equation,
230 + 70 = 200 ℓ
300 = 200 ℓ
=> ℓ = 300 / 200
=> ℓ = 3/2
=> ℓ = 1.5
1. (x² + 24) factors as the difference of two squares (x² - (-24)) where -24 is the square of the complex number i√24 = 2i√6. The factoring is
(x - 2i√6)(x + 2i√6)
2. The square of half the coefficient of the x-term needs to be added: 4.5² = 20.25
This number goes in both boxes.
3. This is the square of (y² +20), so the factorization is similar to that for problem 1.
y⁴ + 40y² + 400 = (y² + 20)² = (y -2i√5)²(y +2i√5)²
