Answer:
a(2) b(-3) c(3) d (-2)
Step-by-step explanation:
first one remember that when u ÷ two negatives it becomes positive
second one try to invert and then multiply the fractions
third one try to invert and then multiply the fractions
fourth one remember that if you ÷ by one negative the product will be negative
The answer to this is 25 hope it helps
X=165/2
I hope this helps I’m not too good at math lol
Answer:
I need numbers to do a step by step
but the formula for the surface area of a cone.
Firstly, you work out the circle, pi x radius squared.
then you work out the cone
You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).
So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:
SA = πr2 + πrl
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
