PLEASE HELP... VERY URGENT... WILL GIVE BRAINLIEST!!!

lakkis [162]

Answer:

Step-by-step explanation:

a) Pythagorean theorem,

altitude² + base² = hypotenuse²

h² + (w² - 1)² = (w² + 1)²

h² = (w² + 1)² - (w² - 1)²

{Compare with (a + b)² - (a -b)² = 4ab where a =w² & b = 1}

h² = 4*w²*1

h² = 4w²

$h=\sqrt{4w^{2}} = \sqrt{2*2*w*w} \\\\\\h = 2w$

b) Area of triangle = $\frac{1}{2}b*h$

$=\dfrac{1}{2}*(w^{2}-1) *2w\\\\= (w^{2}-1)*w = w^{2}*w - 1*w\\\\=w^{3}-w$

c) w =2

Area of triangle = 3w = 3*2 = 6

6 sweets cost 42p altogether how much do 8 sweets cost

Eddi Din [679]

The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
