Multiply the number by 75%
Answer:
(-2x - 1) • (x + 3)
Step-by-step explanation:
3.2 Factoring 2x2 + 7x + 3
The first term is, 2x2 its coefficient is 2 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is 7 .
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 6
2x2 + 1x + 6x + 3
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x+1)
Add up the last 2 terms, pulling out common factors :
3 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x+1)
Which is the desired factorization
Hello!
To find the height of a rectangular pyramid, you use the formula h=3(v/lw)
h= height (what we're trying to find)
v= volume
l= base length
w= base width
So, if you plug in everything, you'll see that the height is 14.
Want to check that you're correct? Use the formula V=lwh/3 to see if you get the same volume as before.
If you plug it in, you'll see that it's the same volume as before, so we have now found, checked, and proven the answer is 14!<span />
Plug in all the values
16 + 13 -10 = 19
19, Hope this helps!
