Find the lateral area of a rectangular prism with l=6, w=4, h=2
lord [1]

Answer:

40 square units

Step-by-step explanation:

The surface area is given by

LA = 2(wh+lh)

where h is the height l is the length and w is the width

We do not include the top or bottom

We know l=6 w=4 and h=2

LA = 2 ( 4*2 + 6*2)

lA = 2( 8+12)

    = 2 (20)

    = 40

Find the value of c that makes the expression a perfect square trinomial. x2 + 9 4 x + c
JulijaS [17]

The value of c is 81/64 for the expression a perfect square trinomial.

<h3>What is an Expression?</h3>

An expression can be defined as a mathematical statement that consists of variables, constants and mathematical operators simultaneously.

It is given that an expression

x² +9/4x +c is a perfect square polynomial

c =?

(a+b)² = a² +2ab+b²

2ab = 9/4

b = 9/8

c = b² = 81/64

Therefore the value of c is 81/64 for the expression a perfect square trinomial.

What is the mean absolute deviation of 275, 252, 248, 240, 240, 225, 215, 214, 189, 184
Sati [7]
Hi , if we want to find the M.A.D of the numbers shown , then we have to add them .
275+252+248+240+240+225+215+214+189+184=2,282
Then we have to divide the number by the total of numbers that we have.
2,282 ÷ 10 =228.2
Then we have to subtract 228.2 by each number that we have.
228.2-275=-46.8
228.2 - 252=-23.8
228.2 - 248=-19.8
228.2 - 240=-11.8
228.2-240=-11.8
228.2-225=3.2
228.2-215=13.2
228.2-214=14.2
228.2-189=39.2
228.2-184=44.2
Then we add those numbers , that gives us 0 , if you don't work with negatives numbers then your answer would be 228 , finally we divide that number by the total of numbers that we have , your answer is 22.8 , if you do work with negative numbers then your answer is 0.

T = 130°

U = 115°

V = 65°

because things on a line equal 180°, so you would subtract 180 by the number to get the full line, and letters across from the other, Like V and the space to the right of 115° would be the same
