Is 172 the area or perimeter.
a. 2 - 4 x 6 + 8 + 2 =
b. 6 + 2 x 4 - 8 + 10 =
The answer would be
A.) ~-12~
because 2-24=-22 -22+8+2=-12
B.)~16~
because 6+8-8+10 and -8+8=0 so 6+10=16
Hope this helps

how do you find the area of a right triangle if you only have the base
Step-by-step explanation:
You can find the area of a right triangle the same as you would any other triangle by using the following formula:
A = (1/2)bh, where A is the area of the triangle, b is the length of the base and h is the height of the triangle; However, with a right triangle, it's much more convenient in finding its area if we utilize the lengths of the two legs (the two sides that are shorter than the longest side, the hypotenuse and that are perpendicular to each other and thus form the right angle of the right triangle), that is, since the two legs of a right triangle are perpendicular to each other, when we treat one leg as the base, then, consequently, we can automatically treat the length of the other leg as the height, and if we initially know the lengths of both legs, then we can then just plug this information directly into the area formula for a triangle to find the area A of the right triangle.
For example: Find the area of a right triangle whose legs have lengths of 3 in. and 4 in.
Make the 4 in. leg the base. Since the two legs of a right triangle are perpendicular to each other, then the length of the other leg is automatically the height of the triangle; therefore, plugging this information into the formula for the area of a triangle, we have:
A = (1/2)bh
= (1/2)(4 in.)(3 in.)
= (1/2)(12 in.²)
A = 6 in.² (note: in.² means square inches)

20. Given the area, find the side length.
Answer:
Step-by-step explanation:
Area of a square = 49a⁸b¹⁰
Side = √49a⁸b¹⁰
= √7²*(a⁴)²*(b⁵)²
= (7a⁴b⁵)²
Side = 7a⁴b⁵

Determine the 10th term of the sequence –17, -13,-9, ...
A. 19
B. -53
C. 36
D. 53
Answer:
-53 (answer : B)
Step-by-step explanation:
hello :
this the arithmetic sequence because :
(-9)-(-13)=(-13)-(-17)= 4 (common difference)
the first term is : A1 = -17
the nth term of an arithmetic sequence is :
An= A1 +(n-1)d ....a common difference is : d
the 10th term is : A10
A10= -17 +(10-1)(4) = -17-36 = -53 (answer : B)

Write an equation of a like that passes through the points (9,5) and (6,7)
Answer:
y=-2/3x+11
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-5)/(6-9)
m=2/-3
m=-2/3
y-y1=m(x-x1)
y-5=-2/3(x-9)
y=-2/3x+18/3+5
y=-2/3x+6+5
y=-2/3x+11

[tex]6^{2} +2^{2} =c^{2} \\36+4=c^{2} \\40=c^{2} \\\sqrt{40} =c\\c=6.32[/tex]
Answer:
Square root of 40, I don't know what the brace is
Step-by-step explanation:
To find side c, you have to use the Pythagorean theorem. A^2+B^2=C^2. In this case A and B are 6 and 2. This means the equation would be 6^2+2^2=C^2. Simplify this to get 36+4=C^2. Add 36 and 4 to get 40. 40=C^2. This would mean that it is square root of 40.
