The first, second, fifth, and seventh are all true
Answer:
Proven
Step-by-step explanation:
We prove the polynomial with factorization. We must first simplify the expression before we can factorize:
4 is the common number and we can take it out of the expression:
We can factorize further with the x term being zero. For this to be true we must have -2x and 2x to cancel out and therefore the expression is proven:
Its B! They have to multiply to get 96 and b is the only one that also adds to get 40
A COEFFICIENT is the numerical factor of a multiplication expression like 3x.
Parts of a multiplication expression.
3x + 6
3 is the coefficient
x is the variable
6 is the constant
3x and 6 are called terms.
Answer:
x = 118
Step-by-step explanation:
1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.
2. (Solving)
Step One: Simplify both sides of the equation by adding like terms.
- (x) + (122 + 103 + 98 + 99) = 540
- x + 422 = 540
Step Two: Subtract 422 from both sides.
- x + 422 - 422 = 540 - 422
- x = 18
