Explanation:
___________________________________________
Note the "distributive property of multiplication" :
___________________________________________a(b+c) = ab + ac ;a(b−c) = ab − ac ;___________________________________________
So; given: " - 4x² (3x - 7) " ;
→ - 4x² (3x <span>−</span> 7) ;
= [ -4x² * 3x ] − [- 4x² * -7 ] ;
= -12x³ − (28x²) ;
= -12x³ − 28x² .

Answer:
The value of c in the equation c =6.
Step-by-step explanation:
In mathematics, a perfect square or a square number is an integer that is the square of an integer. In different words, it is the product of an integer with itself. For example, 9 is a square number because it can be written in 3 × 3.
The normal notation for the square of a number n is not the product n × n, but the equivalent exponentiation n2, which is generally pronounced as "n square". The square number of the name results from the name of the form. The unit area is defined as the area of a unit square (1 × 1). Consequently, a square of lateral length n has the area n2.
Square numbers are not negative. Another way to say that an integer (not negative) is a square is to make its square root an integer again.
For example, √9 = 3, so, 9 is a quadratic number.
A positive integer that has no perfect square divisors other than one is called without a square.
24.2² = 24.2 × 24.2 =585.64=abac.
From above equation, a=5,b=8,c=6.
Answer:
-37
Step-by-step explanation:
Simplifying
74 + 2x = 0
Solving
74 + 2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + 2x = 0 + -74
Combine like terms: 74 + -74 = 0
0 + 2x = 0 + -74
2x = 0 + -74
Combine like terms: 0 + -74 = -74
2x = -74
Divide each side by '2'.
x = -37
Simplifying
x = -37
