Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
Answer:
1. Not accounting for the difference in the base of the exponent when applying the quotient rule.
2. Not subtracting the exponents of the denominator from the exponent of the numerator when applying the quotient rule.
Answer:
Your measurements; Area = 216.108 cm²
Another student's measurements; Area = 216.9404 cm²
- Difference in area could be as a result of human error or perhaps that they made use of different measuring tools.
Step-by-step explanation:
For Your measurements;
Length of rectangle = 20.70 cm
Width of rectangle = 10.44 cm
Area of rectangle is given by; A = length × width = 20.7 × 10.44 = 216.108 cm²
For Another student's measurements;
Length of rectangle = 20.74 cm
Width of rectangle = 10.46 cm
Area = 20.74 × 10.46
Area = 216.9404 cm²
The areas they both obtained are not of equal values and this could be as a result of human error or perhaps that they used different measuring tools.
Answer:
area of trapezium: -
formula...
½(sum of parallel sides)×height=area
=>240=½(12+x)×12
=>240=(12+x)×6
=>240=60+6x
=>6x=240-60
=>6x=180
=>x=180/6
=>x=30cm
therefore, the value of x is 30 cm.
