Got it correct
Answer:
a. y + 9 + x + y + x + 4 + x + 5 = 2x + 2y + 18
b. 30.4cm
c. Area of big rectangle = 9y cm², Area of small rectangle = 4x cm²
d. a = 9y + 4x
e. a = 38.8
Step-by-step explanation:
a. Perimeter = y + 9 + x + y + x + 4 + x + 5
= x + x + y + y + 9 + 4 + 5
= 2x + 2y + 18
b. 2x + 2y + 18 = 2(3.4) + 2(2.8) + 18
= 6.8 + 5.6 + 18
= 30.4cm
c. Formula for area of rectangle: length × breadth
Area of big rectangle = 9 × y
= 9y cm²
Area of small rectangle = 4 × x
= 4x cm²
d. a cm² = (9y + 4x)cm²
e. a = 9y + 4x
= 9(2.8) + 4(3.4)
= 25.2 + 13.6
= 38.8
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 <em>before</em> dividing.
