Estimate rounding the nearest ten, nearest tenth, and nearest one
Firdavs [7]
<span>The tenths place is to the right of the decimal point. Our rounded answer will stop at the tenths place. We use the hundredths place to help us determine the value that needs to be in the tenths place. If the value in the hundredths place is 5 or above "we give it a shove." If the value is four or below, "we let it go." In this example, the number is 6, which is "5 or above." So we give it a shove. This means that we round it up from 5 to 6.</span>

Solve the quadratic equation 4x2 − 121 = 0. Verify your answer using a difference-of-squares factoring method.
Alenkasestr [34]

Answer:

Option d) is correct

That is x equals plus or minus start fraction 11 over two end fraction

Step-by-step explanation:

Given quadratic equation is 4x^2-121=0

To write the given quadratic equation by using a difference-of-squares factoring method:

4x^2-121=0

The above equation can be written as

4x^2-11^2=0

(2x)^2-11^2=0

The above equation is in the form of difference-of-squares

Therefore the given quadratic equation can be written in the form of difference-of-squares

by factoring method is (2x)^2-11^2=0

(2x+11)(2x-11)=0 (which is in the form a^2-b^2=(a+b)(a-b) )

2x+11=0   or   2x-11=0

x=\frac{-11}{2}    or   2x=11

x=\frac{-11}{2}    or   x=\frac{11}{2}

x=\pm \frac{11}{2}

Therefore option d) is correct

That is x equals plus or minus start fraction 11 over two end fraction

58 to x should be the ratio of 6/3 or 1/2 if they are similar.

Find out how much bigger 58 is compared to 6, the matching side on the other polygon.

58/6 = ~9.7

The x side should be half of this, just like it is on the smaller polygon.

9.7/2 = 4.85

4.85 x 3 = 14.55
