Complete Question
Which could be the area of the base of the triangular prism?
[Not drawn to scale)
• 6 ft²
• 10 ft²
• 12 ft²
• 20 ft²
Answer:
6ft²
Step-by-step explanation:
The formula for the base area of a triangular prism is given as:
Area of the base = √s(s-a) (s-b) (s-c)
Where s = (a+b+c)/2
From the attached diagram,
a = 5ft
b = 3ft
c = 4ft
s= (5ft + 3ft + 4ft) ÷ 2
s = 6ft
Area of the base = √ 6( 6-5) (6-3) (6-4)
= √6(1)(3)(2)
= √36
= 6ft²
Therefore, the area of the base of the triangular prism is 6ft²
STEP 1: Find the area of the rectangle.
Area = l×b
Area = 19×6
= 114
STEP 2 = Find the area of the triangle.
Area = 1÷2 × base × height
Area = 1÷2 × 6 × 7
= 21
STEP 3 : Add the areas of the rectangle and the triangle to find the area of the whole figure.
∴ 114+21 = 135
FINAL ANSWER = 135

First one. You can tell because it is linear. If you still do not understand watch a video on it.
Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x−(15x−6)=104
x+−1(15x−6)=104(Distribute the Negative Sign)
x+−1(15x)+(−1)(−6)=104
x+−15x+6=104
(x+−15x)+(6)=104(Combine Like Terms)
−14x+6=104
−14x+6=104
Step 2: Subtract 6 from both sides.
−14x+6−6=104−6
−14x=98
Step 3: Divide both sides by -14.
−14x/-14 = 98/-14
<u>x=-7</u>
Hope this helps!
The answer is 7 instead of 5
