and 10

1 answer:

3 0

$x^2 + 3 = 124 \ \ |-124\\ \\x^2+3-124 = 124 -124 \\ \\ x^2-121 =0\\ \\x^2-11^2=0 \\ \\ (x-11)(x+11)=0\\ \\x-11=0 \ \ or \ \ x+11 =0\\ \\x=11 \ \ or \ \ x=-11 \\ \\Answer : B. \ \ -11 \ and \ \ 11 \\ \\ \\ a^2-b^2=(a-b)(a+b)

ANTONII [103]

Answer:

0.45

3.25

Step-by-step explanation:

16.25 ÷ 5 = 3.25

15.25 - 3.25 × 4 = 2.25

2.25 ÷ 5 = 0.45

Check Answer:

3.25 × 5 = 16.25

0.45 × 4 = 2.25

3.25 - 2.25 = 1

16.25 - 1 = 15.25

Ab is 10. 8 units long if ABC is dilated by a scale factor of k equals 1.3 what is the length of a'b'

Marizza181 [45]

ANSWER

The length of

$A'B'=14.04 \: units$

EXPLANATION

The object length given to us is,

$|AB|=10.8 \: units$

The scale factor of the dilation is,

$k = 1.3$

The image length can be calculated using the formula

$|A'B'| = k \times |AB|$

We substitute the given values into the formula to get,

$|A'B'| = 1.3\times 10.8$

We multiply out to obtain,

$|A'B'| = 14.04 \: units$

Sudhanshu is solving a system representing a race between two remote control cars. The variable x is defined as time in seconds,

choli [55]

It all depends on the speeds of the cars. If they are going the same speed, the lines could never cross. Or they could could cross once, if one car passes the other.
However, if the speeds are changing, then there could be multiple solutions.
