Answer:
11
Step-by-step explanation:
Opposite sides are congruent at parallelograms. So x+16 must be equal to 2x+5. Solve the equation;
2x+5 = x+16
x = 11 .

hope this helps!! just use the formulas and substitute
legs of the triangles
Each triangle 30-60-90 is:
one leg: 15 ft => short diagonal = 2 * 15ft = 30ft
other leg, x:
tan(30) = 15 / x => x = 15 ft / tan(30) = 25.98 ft
=> long diagonal = 2 * 25.98ft = 51.96 ft
side of the rhoumbus = hypotenuse of one triangle
side of the rhombus = √ [ (15)^2 + (25.98)^2 ] = √(900) = 30 ft
Area of the rhombus:
4 * area of one triangle = 4 [base*height/2] = 4*15*25.98/2 = 779.43 ft^2
The shortest distance accross the garden is equal to the side of the rhombus = 30 ft
Answer:
(4, -2)
Step-by-step explanation:
(x,y)
x=4
y=-1/2x=-1/2*4=-2
Answer:1. x<3
2.x>3
Step-by-step explanation:
Number 1.
Step 1: Add 9 to both sides.
7x−9+9<12+9
7x<21
Step 2: Divide both sides by 7.
7x
7
<
21
7
x<3
Number 2.
1x+8>11
Step 1: Simplify both sides of the inequality.
x+8>11
Step 2: Subtract 8 from both sides.
x+8−8>11−8
x>3
leave alike if this help please.
