Answer:

$4x^2-12x+9$

Step-by-step explanation:

we have

$(2x-3)^2$

we know that

$(a-b)^2=a^2-2ab+b^2$

In this problem

$a=2x\\b=3$

substitute in the formula

$(2x-3)^2=(2x)^2-2(2x)(3)+(3)^2$

$(2x-3)^2=4x^2-12x+9$

Water makes about 3/4 of a person’s weight. If a student weighs 100 lbs., how much of his weigh is water?

Reptile [31]

Answer:

75 pounds

Step-by-step explanation:

To solve this problem, find 3/4 of 100.

To multiply fractions, multiply the numerators by each other and the denominators by each other.

3/4 * 100/1

Evaluating 3*100 and 4*1, the fraction becomes 300/4.

Now, divide 300 by 4 to get the final answer. 300/4 = 75. Therefore, 75 pounds of the students weight is water.

evablogger [386]

Answer:

The total yards of cloth needed for the flags = 28

Step-by-step explanation:

Given:

Jake and his dad are making (6,12,18) different types of flags.

Each flag takes $(\frac{2}{3},\frac{3}{4},\frac{5}{6})$ of a yard of cloth.

To find the total yards of cloth needed in all.

Solution:

Flag A :

Each flag requires = $\frac{2}{3}$ of a yard of cloth

Total number of this flag = 6

Total cloth required for this flag = $\frac{2}{3}\times 6 = 4\ yd$

Flag B:

Each flag requires = $\frac{3}{4}$ of a yard of cloth

Total number of this flag = 12

Total cloth required for this flag = $\frac{3}{4}\times 12 = 9\ yd$

Flag C:

Each flag requires = $\frac{5}{6}$ of a yard of cloth

Total number of this flag = 18

Total cloth required for this flag = $\frac{5}{6}\times 18 = 15\ yd$

Thus, total yards of cloth needed for the flags = $4\ yd+9\ yd+15\ yd =28\ yd$
