Evaluate the following expression:p/-3 + (-8)= -8

1 answer:

7 0

P/-3+(-8)=-8
p/-3-8=-8
Add 8 to each side
p/-3-8+8=-8+8
p/-3=0
Multiply both side by 3
p/-3(3)=0(3)
p=0
Check:
p/-3+(-8)=-8
Substitute p with 0
0/-3+(-8)=-8
0-8=-8
-8=-8. As a result, p=0. Hope it help!

The vertices of triangle rst are r(–1,–2), s(2,–1), and t(4,2). If δjkl ∼ δrst and the length of kl is units , what is the lengt

NemiM [27]

Answer:

3.16 units

Step-by-step explanation:

It has been given that the triangles JKL and the triangle RST are congruent.

That implies that, the length of the side JK, KL, and JL is equivalent to the length of the sides RS, ST, and RT respectively.

Now, to find the length of JK we need to find the length of the side RS. The coordinates of the points R and S are $(-1,-2)$ and $(2,-1)$ .

The length of the side RS is equal to the distance between point R and S.

RS $=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$= \sqrt{(2-(-1))^2+(-1-(-(-2))^2}$

$=\sqrt{3^2+(-1+2)^2}$

$=\sqrt{9+1}=\sqrt{10}=3.16$

Now that we have the length of the side RS, and the triangles JKL and RST are congruent therefore, the length of the side JK is 3.16 units.

The measure of the base of a triangle is represented by 4x+3 and the height is 6x represent the area of the triangle as a polyno

Juliette [100K]

Answer:

$12x^2+9x$

Step-by-step explanation:

The formula of the area of a triangle is $\frac{bh}{2}$ . Plugging in the given base and height values, you get $\frac{(4x+3)(6x)}{2}=\frac{24x^2+18x}{2}=12x^2+9x$ . Hope this helps!

A manufacturer of skis offered chain discounts of 10/5/4 to many of its customers. Joe Jones ordered skis that had a total list

kati45 [8]

First,
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550

then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55
127,822.50 * .04 = 5112.90

trade discount = 14950 + 6727.50 + 5112.90
26790.40

hope this help
