Answer:

see explanation

Step-by-step explanation:

JK = 4x + 6 = (4 × 4) + 6 = 16 + 6 = 22

LM = 5x + 2 = (5 × 4) + 2 = 20 + 2 = 22

KL = 2y - 2 = (2 × 8) - 2 = 16 - 2 = 14

MJ = y + 6 = 8 + 6 = 14

So JK = LM and KL = MJ

JKLM is a parallelogram since opposite sides are congruent

Lines l and m are parallel. When they are cut by the two transversals below, a triangle is formed.

marshall27 [118]

Answer:

<2 = 34degrees

Step-by-step explanation:

Find the diagram attached below:

First we need to get <1;

<1 + 74 = 180 (angle on a straight line)

<1 = 180 - 74

<1 = 106degrees

Also, <1 + <2 + 40 = 180 (sum of angle in a triangle)

106+<2 + 40 = 180

146 + <2 = 180

<2 = 180-146

<2 = 34degrees

Find the perimeter of the quadrilateral.

levacccp [35]

Question:

Find the perimeter of the quadrilateral. if x = 2 the perimeter is ___ inched.

The complete figure of this question is attached below

Answer:

<h3>The perimeter of the quadrilateral is 129 inches</h3>

Solution:

The complete figure of this question is attached below

Given that, a quadrilateral with,

Side lengths are:

$4x^2 + 8x\ inches \\\\3x^2-5x+20\ inches \\\\7x + 30\ inches \\\\31\ inches$

The values of the side lengths when x = 2 are

$(4x^2+8x)=(4\times 2^2+8\times 2)=(4\times 4+16)=16+16=32\ inch\\\\(3x^2-5x+20)=(3\times 2^2-5\times 2+20)=(3\times 4-10+20)=12+10=22\ inch\\\\(7x+30)=(7\times 2+30)=14+30=44\ inch$

Perimeter of a quadrilateral = Sum of its sides

Perimeter of given quadrilateral = 32 + 22 + 44 + 31 = 129 inches

Thus perimeter of the quadrilateral is 129 inches

Two minor league baseball players got a total of 292 292 hits. washington had 18 18 more hits than sanchez. find the number of h

koban [17]

Let number of hits by Sanchez be x.

Number of hits by Washington = 18 + x

Total number of hits = 292

x + 18 + x = 292

2x + 18 = 292

2x = 274

x = 137

Hence, Sanchez has 137 hits and Washington has 155 hits.
