Answer:
a=11
Step-by-step explanation:
Let's solve your equation step-by-step.
√a+5=4
Solve Square Root.
√a+5=4
a+5=42(Square both sides)
a+5=16
a+5−5=16−5(Subtract 5 from both sides)
a=11
Check answers. (Plug them in to make sure they work.)
a=11(Works in original equation)
Answer:
(2,3)
Step-by-step explanation:

The answer is (2,3)
Answer:
.
Explaining:
The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle.
In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.
Answer:
Step-by-step explanation:
Use identity : (a + b)² =a² + 2ab + b²
49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²
= (7m²)² + 2 *7m²*10 + 10²
= (7m² + 10)²
= (7m² + 10)(7m² + 10)
Step-by-step explanation:
Given AB = CD
<em>ADDING</em><em> </em><em>BC</em><em> </em><em>ON</em><em> </em><em>BOTH</em><em> </em><em>SIDES</em><em> </em>
<em>WE</em><em> </em><em>GET</em>
<em>AB</em><em>+</em><em>BC</em><em>=</em><em>CD</em><em>+</em><em>BC</em>
<em>THEREFORE</em><em> </em><em> </em><em>AC</em><em> </em><em>=</em><em>BD</em>
