Answer:
4/15 = x
Step-by-step explanation:
(2/6)(8/10) =x
(2)(8) / (6)(10)
16/60
Simplify.
4/15=x
Associative property, that's what Google said
Part A
9x^2 + 24x + 16 = (3x + 4)(3x + 4)length of each side = 3x + 4 units.
Part B:
16x^2 - 25y^2= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y

Answer: y = ⁵/₂ x - 13 OR y + 8 =
⁵/₂ x - 5 </h2>

Step-by-step explanation:</h3>
<u>Find the slope of the perpendicular line</u>
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are <em>negative-reciprocal</em>s of each other.
⇒ if the slope of this line = - ²/₅
then the slope of the perpendicular line (m) = ⁵/₂
<u>Determine the equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-8) = ⁵/₂ (x - 2)
∴ y + 8 = ⁵/₂ (x - 2)
We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
since y + 8 = ⁵/₂ (x - 2)
y = ⁵/₂ x - 13
Answer:
Complementary angles, 65°
Step-by-step explanation:
Attach is the picture missing in the question.
Complementary angles are two angle whoes sum total is 90°.
As given in the picture drawn that whole sum of the angle is 90°, therefore it is a complementary angle.
Now, finding the value of x°
∴ (∵ it is a complementary angle)
subtracting both side by 25°.
⇒
∴ x= 65°
Hence the value of x is 65° and the angles are complementary.
