Answer:
First option: Nine mutiplied by the difference of eighty-six and a number.
Step-by-step explanation:
We have the expression:
9(86−x)
We have a difference of number in parenthesis, meaning that this operation will happen first, and then its result will be multiplied by 9
So, we know that this expression means that 9 will be multiplied by something, and this something is a difference of 86 and a number (86 first, and the other number second).
Then, the correct answer would be:
Nine mutiplied by the difference of eighty-six and a number.
First option is the correct one.
Answer:
56 cm^2
Step-by-step explanation:
Well I gotta explain something so I don’t get reported.
Well first separate into 2 shapes
You got 8*3 and 8*4
Multiply and add those 2 numbers
you’d get 56
Answer:
Option "D" is the correct answer to the following question.
Step-by-step explanation:
Given:
Length of painting = 25 inch
Height of painting = 16 inch
Width of frame = w inch
Find:
Area of Picture with frame
Computation:
New length of painting = 25 + w + w
New length of painting = 25 + 2w inch
New height of painting = 16 + w + w
New height of painting = 16 + 2w
Area = l x b
So,
Area of Picture with frame = [25 + 2w][16 + 2w]
Area of Picture with frame = 400 + 50w + 32w + 4w²
Area of Picture with frame = 4w² + 82w + 400
Answer:
Step-by-step explanation:
The graph shows the profile of your parabolic listening device,
By HL theorem we can conclude that both the triangles are congruent
ΔAED ≅ ΔBEC
<h3>What is HL theorem?</h3>
HL theorem: The Hypotenuse-Leg (HL) Triangle Congruence Theorem is a special case that allows you to show that two right triangles are congruent. If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Jackie made a mistake by determining ΔADE is congruent to ΔCBE
we can't conclude it directly because the angles at D and B may be different
∠E=90° and given that hypotenuse of both the triangles are congruent
AD≅CB and leg of the two triangles are congruent AE≅BE
then by HL theorem we can conclude that both the triangles are congruent
ΔAED ≅ ΔBEC
