Factorise the following 4(x-1)²-9 need solution

kumpel [21]

Answer:x= 5/2 x= -1/2

Step-by-step explanation:

4(x-1)2-9

4(x2-2x+1) - 9

4x2 - 8x + 4 - 9

4x2 - 8x - 5

4x2 +2x - 10x - 5

2x(2x+1) - 5(2x+1)

(2x-5)(2x+1)

Find the length of the missing side in the figure below. a = _______ cm.

WITCHER [35]

Answer:

$\frac{2 \sqrt{177} }{5}$

or

5.32cm correct to 2 decimal places

Step-by-step explanation:

This is a right angled triangle from what I know so we have to apply pythagoras theorem.

${7.1}^{2} = {a}^{2} + {4.7}^{2}$

we need to rearrange this to find a²

${a}^{2} = {7.1}^{2} - {4.7}^{2}$

$a = \sqrt{ \frac{708}{25} }$

This can either be written as a fraction or decimal.

$a = \frac{2 \sqrt{177} }{5}$

OR

$a = 5.32$

correct to 2 decimal places

Add 5/8 inch, 11/16 inch, and 27/32 inch.

noname [10]

Hi,

Work:

Equation;

$\frac{5}{8} + \frac{11}{16} + \frac{27}{32}$

Write all numerators above the least common denominator 32.

$\frac{5 + 11 + 27}{32}$

Calculate the sum of positive numbers.

$\frac{69}{32}$

Simplify (FRACTION RESULT)

$2 \frac{5}{32}$

Or (DECIMAL RESULT)

$2.15625$

Hope this helps.
