Which of the following is a factor of 8x2 + 21x + 10? a) 2x + 5 b) 4x + 5 c) x + 2 d) none of the above

C) x + 2

Step-by-step explanation:

we are given

We can split 21

now, we can use grouping method

now, we can factor it

we can see that x+2 factor only maches

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
