30 = 5/6 of x
30 = 5/6 (x)
30 ÷ 5/6 = x
30 × 6/5 = x
180/5 = x
36 = x

The quadrilateral shown is a rhombus. If AB = 17 and AE = 8, what is the measure of AC? A) 8 B) 12 C) 16 D) 24

Contact [7]

Answer:

C)16

Step-by-step explanation:

assuming the rhombus is named ABCD and E is where the diagonals meet.

Rhombus is a quadrilateral in which

All sides are equal
Opposite internal angles are equal
Diagonals bisect each other at right angles

As rhombus is ABCD , AC is a diagonal which is bisected by E (According to the properties of Rhombus)

therefore AC will be twice of AE which is given to be 8

⇒ Answer is 16

If a number is doubled, and 16 is added to it, the resault is 40. what is the number

Sphinxa [80]

Answer:

The number is 12

Step-by-step explanation:

Let x = number

2x+16 = 40

Subtract 16 from each side

2x+16-16 =40-16

2x = 24

Divide by 2

2x/2 =24/2

x = 12

What should be done to x^2 + 15x in order to create a perfect square?

lana [24]

$\bf \qquad \textit{perfect square trinomial} \\\\ (a\pm b)^2\implies a^2\pm \stackrel{\stackrel{\text{\small 2}\cdot \sqrt{\textit{\small a}^2}\cdot \sqrt{\textit{\small b}^2}}{\downarrow }}{2ab} + b^2 \\\\[-0.35em] ~\dotfill$

$\bf x^2+15x+\boxed{?}^2\implies \stackrel{\textit{we know the middle term is}}{2\sqrt{x^2}\cdot \sqrt{\boxed{?}^2}\implies 2x\boxed{?}}\qquad then\qquad 2x\boxed{?}=15x \\\\\\ \boxed{?}=\cfrac{15x}{2x}\implies \boxed{?}=\cfrac{15}{2}\qquad \impliedby \textit{we should add that much \underline{squared}} \\\\[-0.35em] ~\dotfill\\\\ x^2+15x+\left( \cfrac{15}{2} \right)^2\implies \left(x+ \cfrac{15}{2} \right)^2$
