Answer:
a . 9.66 cm
Step-by-step explanation:
a. rule MDAS
multiple first
4(1)=4
4(√2)=5.66
(4+5.66)=9.66cm
1. lines j and k because they have the same slope.
2.d because -1/3 is the opposite slope of 3 and it passes through that point.
Answer:
-13
Step-by-step explanation:
3x^3 - 2y^-6x^2y^2+xy
x=2/3 and y=1/2
Solve :
3x^3 - 2y^-6x^2y^2+xy
Put value of x and y in this equation
= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)
= -13

Substitute the x-value into the expression and solve it.
-x^{2} - 4x Substitute all the x variables for 3
-3^{2} - 4(3) Use PEMDAS and start with the exponent (-3^{2} = -3 x -3 = 9)
9 - 4(3) Multiply
9 - 12 Subtract
-3
