With decimals, I learnt that if you put a 1 underneath the dot, you'll find the place value of each numeral.
Therefore, the answer to this question is; the value of eight, is 80 because it's in the tenths place.

Solution:

$\sqrt{4x + 13} = x + 2$

First square both sides.

$= > ( \sqrt{4x + 13} ) ^{2} = (x + 2) ^{2}$

Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².

$= > 4x + 13 = {(x)}^{2} + 2 \times x \times 2 + (2) ^{2} \\ = > 4x + 13 = {x}^{2} + 4x + 4$

Now, transpose 4x and 4 to LHS.

$= > 4x - 4x + 13 - 4 = {x}^{2} \\$

Now, do the addition and subtraction.

$= > {x}^{2} = 9 \\ = > x = \sqrt{9} \\ = > x = ±3$

Answer:

x = ± 3

Hope you could understand.

Answer:

$20.63 if you tip on the pre-tax amount

Step-by-step explanation:

You pay $12.99 for the pizza, plus the 8% tax on the pizza, plus the 20% tip of the cost of the pizza, so if you tip on the pre-tax amount, you pay

$12.99(0.08) = $1.04 in sales tax

$12.99(0.2) = $2.60 for the tip

and $4 delivery charge,

so you pay a total of

$12.99 + $1.04 + $2.60 + $4 = $20.63
