since they're similair then similair sides will be proportional
CB is similair to EF
\frac{6}{8}86 = \frac{3}{4}43
same thing if you try with the hypotenuse AB similair to DE
\frac{13.5}{18}1813.5 = \frac{3}{4}43
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
<h3>r=16.</h3>

Answer:
Step-by-step explanation:
Multiply the numbers on each face 5×7, 6×7, 6×4÷2 (for the triangle) remember that there are 2 of each of the faces so the answer to 5×7 multiply that by 2 to get both faces
Answer: 8x³ + 12x² - 16x - 16
<u>Step-by-step explanation:</u>
(4x² - 2x - 4)(2x + 4)
= (2x + 4)(4x² - 2x - 4)
= 2x(4x² - 2x - 4) + 4(4x² - 2x - 4)
= 8x³ - 4x² - 8x + 16x² - 8x - 16
= 8x³ + (-4x² + 16x²) + (-8x - 8x) - 16
= 8x³ + 12x² - 16x - 16
Answer:
15cm
Step-by-step explanation:
scale factor =image diatace/object distance
0.75=x/20
0.75×20=x
15=x
: .x=15cm
