Answer: No
Explanation: In the first problem, 2 is a base and 7 is an exponent.
The 7 that is raised up means we multiply our base together seven times.
This means the same thing as 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 or 128.
On the other hand, 2 × 7 is 14.
It can also be thought of as 2 + 2 + 2 + 2 + 2 + 2 + 2 or 14.
Answer:
No, 2^7 is not the same thing as 2 x 7
Step-by-step explanation:
When you are doing 2 x 7 you multiply 7 by 2. For 2^7, you multiply 2 by 2 7 times.
2 x 7 = 2 x 7
2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2

Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.
Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.
The greatest common factor of 24 and 16 is 8.
You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.
So the greatest number of rows Solise can plant is 8 rows.

b.All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180°. Therefore, the third angle can always be determined.
c.All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
d.All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.
Answers
The correct answer is:
C) All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
Explanation:
Imagine we have an isosceles triangle in which the base angles are each 45°. This would make the vertex angle 90°.
Now imagine we have an isosceles triangle in which the base angles are each 30°. This would make the vertex angle 120°.
Since the angles of the first triangle are not congruent to the angles in the second triangle, the triangles are not similar.
This shows that not all isosceles triangles are similar.
Answer: c. All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
Step-by-step explanation:
An isosceles triangle is a triangle that has two sides of equal length.
Also, the isosceles theorem says that "If two sides of a triangle are congruent, then the angles opposite to these sides are congruent.
"
Consider a triangle with equal angles measure as 30°( which means the third angles will be 120°) measure and another triangle with equal angles measure as 60 ° °( which means the third angles will be 60°).
⇒ It contradicts the similarity criteria for triangle which says that in similar triangles all corresponding angles are congruent .
∴ All isosceles triangles are not similar .The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.

6x(3+2x)=
6i(3+2i)=
Answers
The multiplication of 6x(3+2x) is 18x + 12x² and 6i(3+2i) is 18i - 12 because i² can be written as -1.
What is a complex number?
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that:
The expression:
= 6x(3 + 2x)
After using distributive property:
= 18x + 12x²
= 6i(3+2i)
= 18i + 12i²
= 18i - 12
∵i² = -1
Real and complex numbers are multiplied in exactly the same way, with the exception that we can further condense the complex expression by substituting i² for -1.
Thus, the multiplication of 6x(3+2x) is 18x + 12x² and 6i(3+2i) is 18i - 12 because i² can be written as -1.
