Write the place value of the underlined digit and round each number to the place of the underlined digit plus name the place val
mylen [45]
Each number after the decimal goes in this order:
tenth
hundredth
thousandth
1. Looks like it's under the second number after the decimal. This would be the hundredth. The number after it is less than 5 so you would round down and keep the number 7, which makes 0.67
2. Being under the first number after the decimal, it would be the tenth. The number 8 is higher than 5 so you need to round the 2 up to three, making it 4.3
Do you think you could solve the rest or would you like more examples?

The area of a rectangle is 56 cm. The length is 2 cm more than x and the width is 5 cm less than
AURORKA [14]

The value of x is 6 cm.

Step-by-step explanation:

Given,

Area of rectangle = 56 cm

Length of rectangle = x+2

Width of rectangle = 2x-5

Area = Length * Width

56=(x+2)(2x-5)\\56=2x^2-x-10\\0=2x^2-x-10-56\\2x^2-x-66=0

Factorizing

2x^2+11x-12x-66=0\\x(2x+11)-6(2x+11)=0\\(2x+11)(x-6)=0

Either,

2x+11 = 0          => 2x=-11

Or,

x-6=0               => x=6

As x is added to dimension, it cannot be negative.

Therefore,

The value of x is 6 cm.
