The plate boundaries on earth are made from tectonic plates which are known as rigid slabs of rocks that are composed of SIAL.

The continental and continental plate boundaries are those made of two continents such as Indian and Eurasian plates which collided some million years ago. In collusion, the heavier plate is subducted below the lighter plate. Earthquakes and volcanic continental arcs are formed. The oceanic and the continental plate boundary are those made from the oceanic plates such as the north American and the Pacific plate. Formation of earthquakes, volcanoes, and melting of the crust. They lead to the creation of volcanic arcs, trenches, and faults.

Thus they both lead to earthquakes and subduction of plates and create folded ranges along with faults.

Continent-Continent Convergence Another type of convergent plate boundary is when two continental plates collide. Continental lithosphere is low in density and very thick. Continental lithosphere cannot subduct. So when two continental plates collide, they just smash together.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = - $\frac{7}{2}$

thus the positive value for x is x = 7
