I think the last one doesn't fit in
Answer:
<h3>415 mm</h3>
Step-by-step explanation:
A1=BH
=15mm×7mm
=300mm2
A2=BH
=15mm×5mm
=75mm2
A3=BH
=8mm×5mm
=40mm2
A1+A2+A3=Atotal
300mm2+75mm2+40mm2=Atotal
415mm2=Atotal
Answer:
She did not represent the two original factors correctly on the headers.
Step-by-step explanation:
Adi Algebra titles method is based on the field of values. In the given question the representation of of the product is not correct. The two negative titles must be in the top header so the correct sign in incorporated with the variables.
The vertex angle measures 120 deg.
The base angles are congruent.
Each of the base angles measures x, so
x + x + 120 = 180
2x = 60
x = 30
The altitude separates the isosceles triangle into two 30-60-90 right triangles.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
The hypotenuse is twice the length of the short leg.
Look at one of the right triangles.
The hypotenuse is the leg of the isosceles triangle.
It has a length of 8 units.
The altitude of the isosceles triangle is the short leg of the right triangle.
The short leg is half the hypotenuse, so the altitude of the isosceles triangle is 4 units.
The length of the base of the isosceles triangle is twice the long leg of each right triangle. The long leg of the right triangle measures sqrt(3) times the length of the short leg. Each long leg has length 4sqrt(3). The base is twice that, so the base has length 8sqrt(3) units.
Answer:
Step-by-step explanation:
Here you go mate
Use PEMDAS
Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction
Step 1
-9 =4-(2x+3) Equation/Question
Step 2
-9 =4-(2x+3) Remove parenthesis
-9=-2x+1
Step 3
-9=-2x+1 Subtract 1
-2x=-10
Step 4
-2x=-10 Divide by 2
answer
x=5
Hope this helps
