Use surface area equation 2ab+2bc+2ac plug the numbers in
Answer is -1/3
you would divide both sides by 18 to get the variable on its own and that would leave you with -6/18 and so you have to simplify it by dividing the numerator and denominator by the greatest common factor (6) to get your remaining simplified fraction of -1/3
A.) Simplifying the equation would lead you to 15x^2-3x+9
b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9
Answer:
Error
Step-by-step explanation:
(-94)/5+22/22 Given
-18.8+1 PEMDAS (do -94/5 and 22/2)
-17.8 Add the numbers
After you add the numbers, you take the square root. you will get the answer "Error" because you cannot take the square root of a negative number
Answer:
45
Step-by-step explanation:
by the definition of an isocoles triangle, defined by having two congruent sides, (p-s, r-s), angles SPR and SRP are congruent. by the triangle sum theorem, (internal angles + to 180˚) 90˚ + 2a = 180˚. 2a =90, a = 45
