Answer:
B. 7x - 5
Explanation
Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;
21x^2 + 13x – 20
= 21x^2 + 28x - 15x - 20
= 7x(3x+4) -5(3x+4)
= (7x-5)(3x+4)
Hence one of the factors is 7x - 5
Answer:
No solution
Step-by-step explanation:
16 < 22 - 8 = 22
16 < 14 = 22
This question doesnt make sense, not only is the inequality false, but the equation isn't equal either.
I think it might be a ? it sounds the most reasonable .
Answer:
The area is 155 ft.
Step-by-step explanation:
To find the area if a trapezoid, you have to add the number on top( in this case 13 ft) and then add that with the bottom number(18 ft.) Then, you take that answer and divide it by 2. After that, multiply it with the height(10.) Thus, the answer is 155 ft.
The number 239 is a prime number.
This means that it can only be factored into it's own number times 1
hope this helps
