Answer:
12x+4
Step-by-step explanation:
Cross multiply denominators by numerators so:
8(x)+ 4(x+1)
8x+4x+4
Collect like terms to get 12x+4
(2*3)^2
do the parentheses because of using PEMDAS
P= Parentheses
E= Exponents
M= Multiplication
D= Division
A= Addition
S=Subtraction
(2*3)=6
6^2
6*6 ( write out 6 two times because of the exponent)
Answer: 6*6=36
Step-by-step explanation:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.
Cos 45=7 under root 2 /AB
1 / Under root 2 = 7 under root 2 / AB
AB=14
Ans = 14(b)
