Answer:
-1.9f-18
Step-by-step explanation:
Evaluate like terms. (0.4f-2.3f) & (-13-5)
-2.3f+0.4f-13-5 = -1.9f-18
the reciprocal is 15 by 12
7÷5=1.4 so then 1.4×8=11.2 so your answer is 11.2
18 is the answer.1/8 is 6 so all you need to do is find that and multiply it by the numerator
Answer:
9x^2+21x
Step-by-step explanation:
Area formula for a rectangle: L · W
L=3x
W=3x+7
Since it says multiplying polynomials
I'm guessing you do the Box method
3x(3x+7) = 9x^2+21x
Hope this helps! :)
