Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Multiply the length that you have been given by 2
2: Then, subtract the result from the perimeter.
3: You now have the total length for the remaining 2 sides.
4: Width or height is the number divided by 2.

Answer:
(a) 58 m²
Step-by-step explanation:
The area of a composite figure is found by dividing it into simpler shapes whose area formulas are known.
DivisionExtending the horizontal line to the left, we find it divides the shape into an upper rectangle with dimensions 2 m wide and 4 m high, and a lower rectangle with dimensions 10 m wide and 5 m high.
Rectangle areaThe area of a rectangle is the product of its dimensions:
A = LW . . . . . where L is the length and W is the width
The upper rectangle has an area of ...
A = (4 m)(2 m) = 8 m²
The lower rectangle has an area of ...
A = (10 m)(5 m) = 50 m²
Total areaThe area of the figure is the sum of the areas of the upper and lower rectangles:
A = (8 m²) +(50 m²) = 58 m²
The area of the figure is 58 square meters.
Additional comment
The area can also be figured by considering an enclosing rectangle 9 m high by 10 m wide, for an area of (9 m)(10 m) = 90 m². From this rectangle, a rectangle 4 m high and 8 m wide is removed from the upper right corner. The removed area is (4 m)(8 m) = 32 m². Then the remaining area is ...
90 m² -32 m² = 58 m² . . . . the area of the figure shown

Answer:
x³ + 12x² + 35x
Step-by-step explanation:
"What is (x² + 5x) multiplied by (x + 7)?
First, we can convert this into an algebraic expression!
This can be written as:
(x² + 5x)(x + 7)
We can use the FOIL Method for multiplying binomials.
FOIL: First, Outer, Inner, Last
"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."
FOIL: First: x² × x
x² × x = x³
FOIL: Outer: x² × 7
x² × 7 = 7x²
FOIL: Inner: 5x × x
5x × x = 5x²
FOIL: Last: 5x × 7
5x × 7 = 35x
Add Everything Together!
x³ + 7x² + 5x² + 35x
Simplify:
x³ + 12x² + 35x

120 blocks total
Step-by-step explanation:
All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.
Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.
We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.
5 layers times 24 blocks per layer comes to 120 blocks total.

Answers
Answer:
Intersect/Solution at (1, -2)
Step-by-step explanation:
Equation 1: y = 3x - 5
Equation 2: y = 6x - 8
Step 1 Mutliply each side of equations one by -2
New Equation 1: -2y = -6x + 10
New Equation 2: y = 6x -8
Add the Equations: -y = +2
Multiply each side by -1 and you'll get that y = -2
Plug in -2 to either equation: -2 = 3x - 5
add 2 to each side 0 = 3x -3
add 3 to each side 3x = 3
divide by 3 and you'll get that x = 1
Part A:The solution of the pair of the equation is,x=1 and y=- -2.
Part B: If the two equations are graphed, at point (1,-2) will the lines representing the two equations intersect.
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
A pair of equations is shown below:
y = 3x − 5 -------1
y = 6x − 8 --------2
Substitute the value of y from the equation 1 into equation 2;
3x − 5=6x − 8
3x=-5+8
3x=3
x=1
Put the value of x in the equation 1;
y = 3x − 5 -------1
y=3(1)-5
y=- -2
Hence,the solution of the pair of the equation is,x=1 and y=- -2 and at point (1,-2) will the lines representing the two equations intersect.

Figure A maps to figure B with a scale factor of 1 1/2.
What is the value of x?
Answers
Answer:
x = 6/2 = 3
Step-by-step explanation:
This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.
The scale factor is how much the enlargement is.
The side of Figure A is 2.
So we must multiply 2 ⋅ 1 1/2.
2 ⋅ 1 1/2 (3/2) = 6/2
6/2 is equal to 3.
Therefore, the value of x in Figure B is 3.

Answer: It would be Second leg = 15
Step-by-step explanation:
From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.
Hypotenuse: 25
One leg: 20
Second leg: x
Pythagoras theorem: hypotenuse² = adjacent² + opposite²
c² = a² + b²
25² = 20² + b²
b² = 25² - 20²
b² = 625 - 400
b² = 225
b = √225
b = 15
Therefore, the second leg of the right triangle is 15.
