-28 1/3
Step-by-step explanation:
Answer:
Area of shape B = 312.5 cm²
Step-by-step explanation:
Ratio of Area of A : Area of B = 12² : 15²
Given that area of A is 200 cm², let the area of shape B = x
Therefore:
200:x = 12²:15²
200/x = 144/225
Cross multiply
144x = 200*225
144x = 45,000
x = 45,000/144
x = 312.5 cm²
Area of shape B = 312.5 cm²
Answer:
2 x^2 y^14
Step-by-step explanation:
Simplify the following:
(6 x^3 y^15)/(3 x y)
6/3 = (3×2)/3 = 2:
(2 x^3 y^15)/(x y)
Combine powers. (2 x^3 y^15)/(x y) = 2 x^(3 - 1) y^(15 - 1):
2 x^(3 - 1) y^(15 - 1)
3 - 1 = 2:
2 x^2 y^(15 - 1)
15 - 1 = 14:
Answer: 2 x^2 y^14
Answer:
I will put the answer below, but here is a tip:
Use PEMDAS. PEMDAS IS THIS:
P ( ) parenthesis
E y+x exponents
M x multiplication
D ÷ division
A + addition
S - subtraction
Key:
Property used=PU
Step-by-step explanation:
Part A:
18= 6x(2x-3) PU=( ), y+x, x, & -
Part B:
8+3b-1 PU= y+x, +, & -
Part C:
=12 PU= =
Part D:
14+3n=8n-3x(1-4) PU= ( ), y+x, x, +, & -
Part E:
22x+11-4x-7 PU= y+x, +, & -
Answer:
Remember that 6x^2 and -4x are not like terms. I drew a circle around them since those two will come first then goes the 5 and 3. Hopw this helps, thank you !!
