Answer:
The other diagonal measures 21m
Step-by-step explanation:
In this question, we are tasked with calculating the length of the second diagonal of as Rhombus given the measure of the surface area of the rhombus and the length of the other diagonal
Mathematically, for a rhombus having two diagonals
and
, the area of the rhombus can be calculated mathematically using the formula below;
A = 1/2 ×
× 
From the question, we can identify that A = 157.5
and
= 15m
we input these in the formula;
157.5 = 1/2 × 15 × 
315 = 15 
= 315/15
= 21m
Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
= 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2
so
would be closest to the positive 2 on the number line and 2 notches.

is an irrational number, so it might fall into 3.3 if turned into a decimal.
Step-by-step explanation:
Answer: x = -4 or x = 7
Step-by-step explanation:
x^2 - 3x - 28 =/>
(factor)
(x^2 + 4)(x-7) = 0
x + 4 = 0 or x - 7 = 0
(subtract -4 from 0 and 7 from 0)
x = -4 or x =7

<u>Step-by-step explanation:</u>
Here we have , If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then in the form of a paragraph, explain in complete sentences the next steps necessary to completely solve the equation for x. Let's solve this :
2x - 8 = 5x + 3
⇒ 
⇒
{ subtract 2x from both side }
⇒ 
⇒ 
⇒
{ subtract 3 from both sides }
⇒ 
⇒
⇒
{ divide 3 from both sides }
⇒ 
I=p*r*t
The answer is 1131.20
