Answer:
6a) x = -6
Let's solve your equation step-by-step.
14= 2x + 26
Step 1: Flip the equation.
2x + 26 = 14
Step 2: Subtract 26 from both sides.
2x + 26 − 26 = 14 − 26
2x = −12
Step 3: Divide both sides by 2.
2x/2 = −12/2
x=−6
--------------------
7a) x = 4.25
Let's solve your equation step-by-step.
−30 =4 − 8x
Step 1: Simplify both sides of the equation.
−30 = 4 − 8x
−30 = 4 + −8x
−30 = −8x + 4
Step 2: Flip the equation.
−8x + 4 = −30
Step 3: Subtract 4 from both sides.
−8x + 4 − 4 = −30 − 4
−8x = −34
x=17/4 (Decimal: 4.25)
---------------------------------
8a) x = 8
Let's solve your equation step-by-step.
3(x − 4) = 12
Step 1: Simplify both sides of the equation.
3(x − 4) = 12
(3)(x) + (3)(−4)= 12(Distribute)
3x + −12 = 12
3x − 12= 12
Step 2: Add 12 to both sides.
3x − 12 +1 2 = 12 + 12
3x = 24
Step 3: Divide both sides by 3.
3x/3=24/3
x=8
The answer is 49,152.
You double the numbers as you go, it goes up to 49,152.
Answer:
First Term = 6
Common Ratio = 3
Step-by-step explanation:
According to the Question,
- Given, The sum of the first eight terms in a Geometric Series is 19680 and the sum of the first four terms is 240 .
Thus, & .
- The Sum of n-term of Geometric Mean is Where, r>1 , a=First term of G.P & r=common Ratio .
Now, on solving we get,
(r=1 is not possible so neglect )
So, r=3 Now Put this value in We get a=6 .
Answer:
A. Show that the diagonals form two congruent triangles using the definition of a rhombus and geometric properties. Then, use CPCTC (corresponding parts of congruent triangles are congruent) to show that the opposite interior angles are bisected.
Step-by-step explanation:
Answer choice A is the only one that applies specifically to a rhombus.
The other answer choices are true of triangles and vertical angles in general. They do not relate specifically to the problem at hand.
