Answer:
Step-by-step explanation:
Solve for the value of 
:
-Use <u>Distributive Property</u>:
-Combine like terms:
-Take 
and subtract it from 
:
-Subtract both sides by 
:
-Divide both sides by 
:
-Reduce the fraction to the lowest term by extracting and canceling out 
:
Therefore, the value of is 
.
The answer is true from s away from-
The name Quadratic<span> comes from "quad" meaning square, because the variable gets squared (like x</span>2<span>). However, it is important to not that an expression is only quadratic if and only if the highest degree of a term is 2. Therefore, the quadratic equations from the pool of choices would be as follows:
</span><span>3x^2 + 5x - 7 = 0
</span><span>5x^2+ 15x = 0
</span><span>x^2 - 4x = 4x + 7</span>
22 times 15 and you get 330
Answer:
A) Gilligan can conclude that triangle ABC and triangle SDC are similar.
B) He can conclude that the distance is longer than the hypotenuses of the triangles.
Step-by-step explanation:
A) This is because they are the same shape and have proportionate sizes.
B) This is because if AB = 90 feet, he knows that the distance will be about the same length as the hypotenuses of the triangles.
