Step-by-step explanation:
Answer:
8 inches
Step-by-step explanation:
Use the formula for <u>area of a triangle</u>:
A = bh/2
"A" for area
"b" for base
"h" for height
What we know:
A = 34in²
h = 8 1/2 in
<u>Substitute</u> the known values into the formula
A = bh/2
(34in²) = b(8 1/2 in)/2
<u>Isolate "b"</u> to solve for the length of the base
(34in²) * 2 = b(8 1/2 in)/2 * 2 Multiply both sides by 2.
(68in²) = b(8 1/2 in)
(68in²)/(8 1/2 in) = b(8 1/2 in)/(8 1/2 in) Divide both sides by (8 2/1 in)
(68in²)/(8 1/2 in) = b Simplify and move variable to left
b = (68in²)/(8 1/2 in)
How to divide a mixed fraction:
Convert to improper fraction
Reformat division
Flip the second fraction
Combine into numerator
Length of base
Therefore the base is 8 inches.
Answer:
i think 300 but im not sure
Step-by-step explanation:
12 ft I think because 18 would be too long
-4(2m+5)=38
-8m-20=38
-8m=58
-m= 58/8
M=-29/4
