<h3>
Answer: 21.4 square meters</h3>
Work Shown:
A = area of the front triangular face
A = base*height/2
A = 2*1.7/2
A = 1.7
L = lateral area
L = (perimeter of the base)*(depth)
L = (2+2+2)*(3)
L = 18
SA = total surface area of a triangular prism
SA = 2*A+L
SA = 2*1.7+18
SA = 21.4 square meters
Answer:
3 movie tickets would cost 44.8 5 popcorns would cost 85
Step-by-step explanation:
29.4 divided by 2 equals 14.7
29.4 plus 14.7 equals 44.8
68 divided by 4 17
68 plus 17 equals 85
Answer:
the average height is between 65 and 72 inches
Step-by-step explanation:
Answer:
Look for perpendicular lines or corresponding angles or alternate interior angles.
Step-by-step explanation:
When you want to show that a quadrilateral is a parallelogram you need to show that the oposite sides are parallel. In order to show that two segments are parallel there are various theorems and definitions you can use.
1 - Remember that two lines perpendicular to the same segment are parallel.
2 - When two lines are cut by a secant and their alternate interior angles are congruent, then the resulting lines are parallel, I will attach a drawing to illustrate what I am saying.
3 - When two lines are cut by a secant and their CORRESPONDING angles are congruent, then the resulting lines are parallel, I will also attach a drawing to illustrate what I am saying.
4x^2+23x+15=0
Δ=23^2-4*4*15=529-240=289
x1= (-23+17)/8=-6/8= -3/4
x2= (-23-17)/8=-5
4x^2+23x+15= 4(x+3/4)(x+5)=(4x+3)(x+5)
