<h3>
Answer: 7(x+3)(x-2)</h3>
========================================
Explanation:
First factor out the GCF 7
7x^2 + 7x - 42
7*x^2 + 7*x + 7*(-6)
7(x^2 + x - 6)
Now focus on factoring x^2+x-6
We need to find two numbers that multiply to -6 and add to 1. Those values are 3 and -2. That means x^2+x-6 factors to (x+3)(x-2).
The 7(x^2 + x - 6) then turns into 7(x+3)(x-2)
The factor out front, the "7", is the integer factor. The other factors (x+3) and (x-2) are binomial factors.
Answer:
Step-by-step explanation:
y + 1 = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 13
Sorry but i only know the answer to number 3

A rational number is a number that can be written as a fraction where numerator and denominator are both integers (and the denominator is not zero).
Since 0.57 = 57/100, so the number 0.57 can be written as a fraction where the numerator (57) and denominator (100) are both integers. </span>
Yeah because he was at least 80% and when you add the grain and carbon that was total. Then divide the carbon. It will be 80%
