(5x-8)(2x + 6)
Answer: 8
Step-by-step explanation:
Answer:
10x² + 14x - 48
Step-by-step explanation:
F: (5x)(2x) = 10x²
O: (5x)(6) = 30x
I: (-8)(2x) = -16x
L: (-8)(6) = -48
combine the two middle terms to get 14x
10x² + 14x - 48
Use the side -splitter theorem to solve for x in the triangle below
Answer:
x = 30
Step-by-step explanation:
Side splitter theorem,
"If a line intersects two sides of a triangle and is parallel to the third side of the triangle, will divide the sides proportionally."
Therefore, ratio of the parts of two sides intersected will be proportional.
[tex]\frac{3}{15}= \frac{6}{x}[/tex]
[tex]x=\frac{6\times 15}{3}[/tex]
[tex]x=30[/tex]
Therefore, [tex]x=30[/tex] will be the answer.

write an exponential function in the form y = ab^x that goes through points (0,20) and (8,5120)
9514 1404 393
Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x

What do all rectangles have in common? Choose ALL the correct answers.
no sides
the same length
all sides
the same length
4 sides
4 right angles
Answer:
4 right angles
Step-by-step explanation:
All rectangles have 4 right angles in common.
All the rectangles have all their right angles (there are four of them) in common. The bottom-left box correctly states the commanality.
What is a rectangle?A rectangle consists of 4 sides, connected end to end, such that all the adjacent sides are at right angles (90°) with each other.
Due to four corners in a rectangle, and all corners internally having right angles, so all the rectangles have 4 right angles in common.
It isn't necessary for all the four sides being equal (its for square though, a special case of rectangles). (we assume that the fourth box is stating that all 4 sides of all rectangles are same in length)
But all the rectangles have their oppositely faced side pairs having equal length within their pairs.
Also, even if all the rectangles have 4 sides, but one rectangle can have some other lengthed sides, and another rectangle can have its sides of other lengths.
Thus, all the rectangles have all their right angles (there are four of them) in common (well right angle is not the only thing they've got in common, like they've got exterior angles common, 4 vertices etc). The bottom-left box correctly states the commanality.

Which equation represents y = x2 + 12x + 27 in vertex form?
y = (x + 6)2 − 9
y = (x + 6)2 + 21
y = (x + 6)2 + 9
y = (x + 6)2 + 27
Answer:
y = (x + 6)² - 9Step-by-step explanation:
Complete the square:
y = x² + 12x + 27
= x² + 2*6*x + 6² - 6² + 27
= (x + 6)² - 36 + 27
= (x + 6)² - 9

Solve for X. Grade 7 math.
Answer:
x=8
Step-by-step explanation:
9x - 8 = 64 (being vertically opposite angles)
9x = 64 + 8
x=72/9
x=8
9x -8
9*8 -8
72-8
64
The value of x will be equal to 8.
What are opposite angles?There are four angles created when two lines cross. There are two sets of non-adjacent angles among these angles. These are referred to as vertically opposite angles, opposite angles, or vertical angles. These angles are all of the same sizes.
The value of x will be calculated by equating the two opposite angles to each other.
9x - 8 = 64 (being vertically opposite angles)
9x = 64 + 8
x=72/9
Divide the number 72 by 9 to get the value of x.
x=8
Calculate the angle by putting the value of x.
Angle = 9x -8
Angle = 9x 8 -8
Angle = 72-8
Angle = 64
Therefore, the value of x will be equal to 8.
