Step-by-step explanation:
it is really not complicated. we only need to type the numbers into the calculator.
so, what's the problem ? you don't know what a perimeter is ? it is the circumference, the total way you have to go when waking all around the figure.
you don't know the formulas for the areas of specific figures ?
let's start :
a)
the area of a rectangle is length×width. I hope you know this at least since first grade.
the important thing here is : the result is in² and not just in. it means an area counts the little squares that fill that area.
A = 30×8 = 240 in²
the perimeter, as explained, is the whole way around it. so, in the end, as you can easily see, we would have to go 2 times the long side and 2 times the short side.
the result is in (just a length, a distance not an area, not a cube, ...).
P = 2×30 + 2×8 = 60 + 16 = 76 in
b)
the area of a triangle is
baseline × height / 2
in this case (a right-angled triangle) we can assume one of the sides enclosing the 90 degree angle as baseline and the other as height (since there is already a 90 degree angle between them).
and again, the result is ft². we could express it also e.g. as in², but since the basic measures are in ft, it makes it better understandable to use ft².
A = 12×5/2 = 6×5 = 30 ft²
the perimeter is even easier than for the rectangle, as we have one side less to count.
and as before, we stay with ft.
P = 12 + 13 + 5 = 30 ft
c)
this is the only more special case.
but it is still easy.
the area is baseline × height.
and our unit of measurement here is cm, so the result will be cm².
A = 10×2 = 20 cm²
the perimeter is the same principle as with a regular rectangle, as the angles don't matter. only the side lengths matter.
so, again, while waking around it, we have to pass 2 times the long side and 2 times the short side.
and the result is a length, a distance again, so, it is cm.
P = 2×10 + 2×4 = 20 + 8 = 28 cm

Answer:
6) a) 69 b) 97 c)86 d)71
7) A.
Step-by-step explanation:
6)
a) -1-[9(-8)]-2 = -1 - (-72) -2
= -3 + 72 = 69
b) 81 + 4² = 81 + 16
= 97
c)12×7 + 6÷3 =(12×7)+(6÷3)
= 84 + 2
=86
d)74 + 9 ÷ -3 = 74 + (9÷ -3)
= 74 - 3
= 71

Step-by-step explanation:
Change the following mixed expressions to fractions and then simplify the complex fractions.
Answer:
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]
Step-by-step explanation:
One is given the following expression:
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
Now simplify this expression, then cancel common terms in the numerator and denominator,
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

I WILL MARK AS BRAINLIEST! Write an Equation that represents the points in the table
Answer:
y = 3x + 5
Step-by-step explanation:
Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).
Substitute the information for the variables in the slope-intercept form equation.
y = mx + b
m = slopeb = y-intercept valueAnswer:
y=3x +5
