1. since A^2= 36x^2, a=? 2. since b^2= 49, b=?

Wewaii [24]

Answer:

Step-by-step explanation:

36x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

then

36x² - 49

= (6x)² - 7²

= (6x - 7)(6x + 7)

Thus 6x - 7 is a factor of the expression

The radius of a circle is 18 yards. What is the circle's area? Use 3.14 for .

IrinaVladis [17]

Solution:

We know that:

Radius: 18 yards
πr² = Area of circle
π = 3.14

Finding the area of the circle:

(π)(r²) = Area of circle
=> (3.14)(18²) = Area of circle
=> (3.14)(324) = Area of circle
=> Area of circle = 3.14 x 324 = 1017.36 yards²

$\bf \cfrac{18}{32}\implies \cfrac{2\cdot 3\cdot 3}{2\cdot 2\cdot 2\cdot 2\cdot 2}\implies \cfrac{3\cdot 3}{2\cdot 2\cdot 2\cdot 2}\implies \boxed{\cfrac{9}{16}}\qquad \checkmark \\\\[-0.35em] ~\dotfill\\\\ \cfrac{27}{48}\implies \cfrac{3\cdot 3\cdot 3}{2\cdot 2\cdot 2\cdot 2\cdot 3}\implies \cfrac{3\cdot 3}{2\cdot 2\cdot 2\cdot 2}\implies \boxed{\cfrac{9}{16}}\qquad \checkmark$

12 The value of x must be greater than a .0 B.1 C.3 D.7

Likurg_2 [28]

Answer:

must be greater than 7

Step-by-step explanation:

using pythagoras theorem

a^2=b^2-c^2

x^2=15^2-12^2

x^2=225-144

x^2=81

take square root both sides

√x^2=√81

x=9

and 9 is greater than 7
