Answer: c and e
explanation: put the equation in the graphing calculator and look at the graph and table the answer will show
Answer:
x = 14
Step-by-step explanation:
Since they are similar triangles, their sides are proportional
12 : 15 :: 8 : x - 4
Product of extremes = Product of means
12 × ( x- 4 ) = 15 × 8
12x -48 = 120
12x = 120 + 48
12x = 168
x = 168/12
x = 14
Answer:
b. 80
Step-by-step explanation:
Answer:
x^2+4x
Step-by-step explanation:
Use the Foil formula
Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
