<u>Answer:</u> The given statement is true.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.
There are some rules to detect the significant figures in a number:
- All digits ranging from 1 to 9 are always considered significant.
- Every non-zero number is always considered significant. For example, 274, 2.74, and 27.4 all have three significant figures.
- All zero’s that are present between the integers is always considered significant. For example, 5007, 5.007, and 50.07 all have four significant figures.
- All zero’s preceding the first integer is never considered significant. For example, 0.0089 has two significant figures.
- All zeros that are present after the decimal point are always significant. For example, 4.800, 48.00, and 480.0 all have four significant figures.
<u>Rule applied when numbers are added or subtracted:</u>
The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.
Hence, the given statement is true.
6(x)²
<u>explanation</u>
g.c.f : 24(x)² and 30(x)²y
factor 24(x)²
2 * 2 * 2 * 3 * x * x
factor 30(x)²y
2 * 3 * 5 * x * x * y

Answer:
x = - 7, x = 3
Step-by-step explanation:
To find the x- intercepts let f(x) = 0 , that is
x² + 4x - 21 = 0
Consider the factors of - 21 which sum to give the coefficient of the x- term (+ 4)
The factors are + 7 and - 3, since
7 × - 3 = - 21 and 7 - 3 = + 4, then
x² + 4x - 21 = 0
(x + 7)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 3 = 0 ⇒ x = 3
Answer:
<em>H </em>(20) =<em> E</em>
380
Step-by-step explanation:
So, Rana is trying to <em>multiply her hours with her earnings to get the product</em>, that's where the variable<em> E</em> is. <em>H</em> stands for hours, and so you will <em>multiply it by 20 </em>because that's how much she gets per hour.
