Answer:
5/8 + 7/12 =29/24
Step-by-step explanation:
The answer is A. 243, -729
The pattern of this is that they multiply each number by -3.
3*-3=-9
-9*-3=26
27*-3=-81
So you have to multiply -81 by -3. Then multiply that by -3 to get the second number
-81*-3=243
243*-3=-729
Answer:
length measure of Pillow = 1.4 m
Step-by-step explanation:
Volume of Wedge = (area of base triangle) * length
Volume of Wedge = (1/2) * base * height * Length
base = 1 m
height = 0.5 m
Length = L m
Volume = 0.35 m³
=> (1/2) * 1 * 0.5 * L = 0.35
=> (0.5/2)L = 0.35
=> (0.5/2)L * 2 = 0.35 * 2
=> 0.5L * 2 = 0.7
=> 0.5L / 0.5 = 0.7 / 0.5
=> L = 1.4

Answer:
Step-by-step explanation:
(x²-6x-3)(7x²-4x+7)= ?
Multiply each term of 2nd bracket with the 1st bracket:
=7x²(x²-6x-3) -4x(x²-6x-3) +7(x²-6x-3)
=7x^4-42x^3-21x^2-4x^3+24x^2+12x+7x^2-42x-21
Now solve the like terms:
=7x^4-46x^3+10x^2-30x-21
Therefore the answer is (x²-6x-3)(7x²-4x+7)=7x^4-46x^3+10x^2-30x-21 ....
