Answer:
25% decreased by 60% is 10
Step-by-step explanation:
New value =
25 - Percentage decrease =
25 - (60% × 25) =
25 - 60% × 25 =
(1 - 60%) × 25 =
(100% - 60%) × 25 =
40% × 25 =
40 ÷ 100 × 25 =
40 × 25 ÷ 100 =
1,000 ÷ 100 = 10

(7 + V6 )^2
Answer:
36V²+84V+49
Step-by-step explanation:
since it is (7+6V) in two places,therefore

Use A Diagram To Show That (3x+1)(x+2) Is Equivalent To 3x2+7x+2. Show Your Work.
Is (x+4) Equivalent To 2x2+8x+8? Explain Or Show Your Reasoning.
Answer:
1) Please find attached the diagram showing the answer to the question
The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares
∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2
2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18
Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8
Step-by-step explanation:
1) In the attached diagram, we have;
For x = 1
(3x + 1)(x + 2) = (3 + 1)(1 + 2)
Therefore, the length of the sides of the rectangle are;
Height = 4, and Width = 3
For x = 1, x² = 1² = 1
∴ 3·x² = 3, 7·x = 7 × 1 = 7, and 2 = 2
Therefore, from the diagram, we have;
The area = (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares
∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2
The diagram for when x = 3 is also included
2) For (x + 4)², we have;
When x = 1, (x + 4)² = (1 + 4)² = 25
However;
When x = 1, 2·x² + 8·x + 8 = 2 × 1² + 8 × 1 + 8 = 18
Therefore;
(x + 4)² is not equivalent to 2·x² + 8·x + 8
1) Please find attached the diagram showing the answer to the question
The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares
∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2
2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18
Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8
Step-by-step explanation:

For x = 1
(3x + 1)(x + 2) = (3 + 1)(1 + 2)
Therefore, the length of the sides of the rectangle are;

Therefore;
(x + 4)² is not equivalent to 2·x² + 8·x + 8

Jessica started the school year when she was 64.15 inches tall. She grew 2.87 inches during the school year. How tall, in inches, was Jessica at the end of the year? Show your work.
Answer:
67.02 inches
Step-by-step explanation:
If Jessica started out 64.15 inches and grew 2.87 inches then you know that you must add these together.
64.15 + 2.87 = 67.02
Jessica is 67.07 inches at the end of the school year.

write an equation that represents the line. (-3,-6) and (2,-2) use exact numbers
Given:
The line passes through (-3,-6) and (2,-2).
To find:
The equation of line.
Solution:
If a line passes through two points [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex], then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through (-3,-6) and (2,-2). So, the equation of line is
[tex]y-(-6)=\dfrac{-2-(-6)}{2-(-3)}(x-(-3))[/tex]
[tex]y+6=\dfrac{-2+6}{2+3}(x+3)[/tex]
[tex]y+6=\dfrac{4}{5}(x+3)[/tex]
[tex]y+6=\dfrac{4}{5}(x)+\dfrac{4}{5}(3)[/tex]
Subtract 6 from both sides.
[tex]y=\dfrac{4}{5}(x)+\dfrac{12}{5}-6[/tex]
[tex]y=\dfrac{4}{5}(x)+\dfrac{12-30}{5}[/tex]
[tex]y=\dfrac{4}{5}(x)+\dfrac{-18}{5}[/tex]
[tex]y=\dfrac{4}{5}(x)-\dfrac{18}{5}[/tex]
Therefore, the equation of line is [tex]y=\dfrac{4}{5}(x)-\dfrac{18}{5}[/tex].

please solve both questions, i'm very confused! thank you
Answer:
Step-by-step explanation:
These types of problems can be solved with substitution.
We just have to translate the word problem into math.
#1:
F = family, I = individual
[tex]F + I = 188\\95F + 42I = 12,507[/tex]
[tex]F = 188-I\\95(188-I) + 42I = 12507\\17860 - 95I + 42I = 12507\\-53I = -5353\\I = 101\\\\F + I = 188\\F + 101 = 188\\F = 87[/tex]
87 Families, 101 individuals
#2:
The perimeter is 899 meters. The perimeter can be defined as:
[tex]2L + 2W = P\\2L + 2W = 899[/tex]
We are also given that
[tex]2L = W - 100\\so\\2L + 2W = 899\\W- 100 + 2W = 899\\3W = 999\\W = 333\\\\L = \frac{W-100}{2} = \frac{333-100}{2} = \frac{233}{2}[/tex]
W = 333 meters, L = 233/2 meters

4) A TV is on sale. The TV has been reduced by 20%. The sale price is £540. What was the
original price of the TV?
Answer:
675
Step-by-step explanation:
If the price is 20 % off, then we will pay 100-20 = 80 percent of the original price
Let x be the original price
x* 80% = 540
Change to decimal form
x * .80 = 540
Divide each side by .80
.80x / .80 = 540/.80
x =675
The original price is 675
