So I have this question I cannot figure out 3w+w2+1=10−w
Answer:
Answer: w is 1.6 or. -5.6
Step-by-step explanation:
• I guess the question asks to find the value of w
[tex]{ \rm{3w + {w}^{2} + 1 = 10 - w }}[/tex]
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
[tex]{ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\ \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}[/tex]
• let's solve the equation using the quadratic formular
[tex] \hookrightarrow \: { \tt{w = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} }} \\ [/tex]
a is 1b is 4c is -9• Substitute following the mathematical operation rules:
[tex]{ \rm{w = \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times - 9) } }{(2 \times 1)} }} \\ \\ { \rm{w = \frac{ - 4 \pm \sqrt{52} }{2} }}[/tex]
• split the result:
[tex]{ \rm{either \: \{w = \frac{ - 4 + \sqrt{52} }{2} \} \: \: or \: \: \{w = \frac{ - 4 - \sqrt{52} }{2} \} }} \\ \\ { \rm{either \: \{w = 1.6 \} \: \: or \: \: \{w = - 5.6 \}}}[/tex]

The length of a rectangle is 5cm more then the width. the perimeter of the rectangle is 38cm.find the length and width of the rectangle?
Answer:
Length - 12
Width - 7
Step-by-step explanation:
38 = 2((5+x) + x)
38 = 10 +4x
28=4x
x=7
7+5=12
Given : The length of a rectangle is 5cm more then the width. The perimeter of the rectangle is 38cm. Find the length and width of the rectangle?
Solution : According to the question, here we are given that the length if the rectangle is 5m more than its breadth and so the perimeter of the rectangle is 38cm. So, for this let's check the steps below
Let's assume the breadth be B
So, as we got that length is 5cm more than Breadth which is B + 5cm
Perimeter is 38cm
★ Perimeter = 2(Length + Breadth) ★
Perimeter = 2(B + 5cm + B) 38cm = 2(2B + 5cm) 38cm/2 = 2B + 5cm 19cm - 5cm = 2B 2B = 14cm B = 7cmFinding Length
Length = B + 5cm = 7cm + 5cm = 12cm
Finding Breadth
Breadth(Width) = B = 7cm
Therefore, Width is 7cm whereas Length is 12cm

Answer:
x=34º
Step-by-step explanation:
a line always = 180º
so y+81=180
y=99º
a triangle is also always 180º total
so x+y+47=180
x+99+47=180
x+47=81
x=34
x+y+z=63x−2y+2z=2−2x−y+3z=−4
Enter your answer, in the form (x,y,z), in the boxes in simplest terms.
Answer:
(2 , 3, 1)
Step-by-step explanation:
x + y + z = 6 ..(1)
3x - 2y + 2z = 2 ..(2)
-2x - y + 3z = -4 ..(3)
(1)*3-(2): 5y + z = 16 ..(4)
(1)*2+(3): y + 5z = 8 ..(5)
(4)*5-(5): 24y = 72 y = 3
(4): 5*3 + z = 16 z = 1
(1): x + y + z = x + 3 + 1 = 6 x = 2
First, complete the sentence to show how the figure can be decomposed into triangles and rectangles with the fewest number of pieces.
Then find the area of the divisions.
Answer:
The figure will have 2 triangles and 2 rectangles .
The triangles have a combined area of 12 m2.
The rectangles have a combined area of 25 m2.
The figure has a total area of 37 m2.
The figure will have a triangle ABC, a triangle ACD, and a rectangle GDFE.
The total area of the triangles = 26 m²
The total area of the rectangles = 12 m²
The total area of the figure = 38 m²
Given,
The figure is given.
We need to complete the sentence to show how the figure can be decomposed into triangles and rectangles with the fewest number of pieces.

Area of triangle ABC
= 1/2 x 6 x 4
= 12 m²
Area of triangle ACD.
= 1/2 x 7 x 4
= 14 m²
The total area of the triangles.
= 12 + 14
= 26 m²
Area of the rectangle EFDG
= 4 x 3
= 12 m²
The total area of the figure.
= 26 + 12
= 38 m²
Thus,
The figure will have a triangle ABC, a triangle ACD, and a rectangle GDFE.
The total area of the triangles = 26 m²
The total area of the rectangles = 12 m²
The total area of the figure = 38 m²

The total cost of a pizza and 3 drinks is $19. The price of the pizza is $10 and each drink is the same price, d. 6) Which model represents the situation?
The total cost of pizza and drinks, is an illustration of a linear function.
The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
The given parameters are:
[tex]\mathbf{Total =19}[/tex]
[tex]\mathbf{1\ pizza =10}[/tex]
[tex]\mathbf{1\ drink =d}[/tex]
The cost of 3 drinks will be 3d
The total cost would then be:
[tex]\mathbf{Total = 10 + 3d}[/tex]
Substitute 19 for Total
[tex]\mathbf{10 + 3d = 19}[/tex]
Rewrite the above equation as:
[tex]\mathbf{3d + 10 = 19}[/tex]
Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
