Answer:
[tex]108 in^{2}[/tex]
Step-by-step explanation:
Separate it into 2 parts:
The first would be that the length and width of the smaller rectangle would be, 7 in. and 6 in.
7 x 6 = 42 in^2
The second would be that the length and width of the larger rectangle would be, 11 in. and 6 in.
11 x 6 = 66 in^2
Total:
66 + 42 = 108 in^2
Answer:
108 [tex]in ^2[/tex]
Step-by-step explanation:
This polygon consists of two rectangles, one in the top-right hand corner and another in the bottom. To divide these two rectangles, imagine a line extended from the central horizontal line in the polygon. As I work the problem, remember that the formula for the area of a rectangle is [tex]A=l * h[/tex], where A is the area of the rectangle, l the length of the rectangle (one of the sides), and h is the height of the rectangle (the length of a side perpendicular to l).
Starting with the top-right rectangle:
We already know one of the sides of the rectangle is 4 in, so let's imagine this to be h, because it is the height of the rectangle. Finding l is more complicated. We know the length of the larger rectangle is 12 in (more on that later) and the 6 in length is the part of the length that is not a part of the top-right rectangle. This, since the vertical line all the way to the right is straight, the length is the difference between these two lengths, or:
[tex]l=12-6=6[/tex] in
Now that we know l and h, we can evaluate the area of the first rectangle, which is
[tex]A= 6 *4= 24[/tex] in^2
Now for the bottom rectangle:
We know both l and h for this rectangle, which are 12 in and 7 in respectively. Using the area formula for a rectangle above:
[tex]A=12*7=84[/tex] in^2
Since the polygon contains both rectangles, its area is the sum of the areas of the two rectangles. Thus,
[tex]A=24+84=108[/tex] in^2

Jake is building a fence around his property. He wants the perimeter to be no more than 100 feet. He also wants the length to be at
least 10 feet longer than the width. If he builds his fence according to these limits, which would be the maximum possible width of
the fence?
Answer:
C
Step-by-step explanation:
Let the length be l and width be w.
The perimeter will be 2 lengths + 2 widths = 2l+2w
2l+2w cannot be more than 100ft
[tex]21+2w \leq 100[/tex]
Also, the length has to be at least 10ft longer than the width.
[tex]l\geq w+10[/tex]
If we substitute w=20, l=30. 2l+2w can be equal to 100 but not over it.
If w=20 and l=30, 2w+2l = 40+60 = 100.
Hence the maximum length of the width of the fence is 20 ft. C

Hi!pls can u help me factorise this
50d^2 - 98e^2
Factor out 2.
2(25d^2 - 49e^2)
We now factor the difference of two perfect squares within the parentheses.
2(5d - 7e)(5d + 7e)
This is as far as we can factor.
Done!
The factor of the expression into an equivalent form 50d²- 98e² would be; 2(5d - 7e)(5d + 7e)
What is factorization?Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
We are given that expression is given that 50d²- 98e².

A right triangle is displayed.
The area of the right triangle is
A. 24 in ^2
B. 48 in ^2
C. 432 in ^2
D. 864 in ^2
Answer:
You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

Monica goes to a stationery shop to buy pens and pencils. She has $35 in pocket change, and she's looking to buy pens for $7 each and pencils for $2 each.
Write an inequality to describe the possible number of pens and pencils that Monica can buy. If Monica buys 3 pens, what is the maximum number of pencils she
can buy?
Answer:
7 pencils
Step-by-step explanation:
Let x equal the number of pencils Monica buys and y equal the number of pens.
The expression would then be 2x + 7y ≤ 35. Plugging in 3 for y:
2x + 7(3) ≤35
2x +21 ≤ 35
2x ≤ 14
