Answer:
Step-by-step explanation:
As 5 ⋅ 5 ⋅ 7 ⋅ 7 ⋅ 7 = 5² ⋅ 7³ = 8575
Exponential notation: 5² ⋅ 7³
Decimal Notation: 8575
i) 3 ⋅ 8 ⋅ 7 ⋅ 7 ⋅ 7 ⋅ 8 = 3 . 7³ . 8² = 65856
Exponential notation: 3 . 7³ . 8²
Decimal Notation: 65856
ii) 7 ⋅ 7 ⋅ 7 ⋅ 7 ⋅ 6 ⋅ 3 = 3 . 6 . 7⁴ = 43218
Exponential notation: 3 . 6 . 7⁴
Decimal Notation: 43218

This Must Only Have One Solution, Because The Right Side Of The Equation Is Just Plainly Ten. Lets Solve This:
5x + 3x - 4 = 10
Add Four To Both Sides To Begin Simplifying.
5x + 3x = 14
Now, Combine Like Terms.
8x = 14
Divide:
8x/8 = 1X = X
14/8
X = 14/8
14/8 = 1.75
X = 1.75
Check:
(5 * 1.75) + (3*1.75) - 4 = 10
8.75 + 5.25 - 4 = 10
14 - 4 = 10
10 = 10.
This Is True, So X Does Equal 1.75
Answer:
4 1/5
Step-by-step explanation:
25=5x+4.
We move all terms to the left:
25-(5x+4.)=0
We add all the numbers together, and all the variables
-(5x+4)+25=0
We get rid of parentheses
-5x-4+25=0
We add all the numbers together, and all the variables
-5x+21=0
We move all terms containing x to the left, all other terms to the right
-5x=-21
x=-21/-5
x=4+1/5
Answer:- B , C and F are the right options.
Explanation:-
1. HA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
2. HL can be a reason to show given triangles are congruent as the triangles are right triangle with equal legs and hypotenuse.
3. SAS can be a reason to show given triangles are congruent as there are two congruent sides in both triangles and included angles ∠A=∠D=90° [right angle].
4. LA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
5. AAS cannot be a reason to show given triangles are congruent as it is not given that they have two angles common in both the triangles.
6.SSS can be a reason to show given triangles are congruent as it is shown that all the sides of one triangle is congruent to the other.
It is obviously the third one because c is the third letter in the alphabet
