Answer:
B C F
Step-by-step explanation:
If you reduce those answer and try to find the square roots, the decimals are terminating and never ending, while the others are perfect squares.
A. 10g4h9
-5gh4(-2g3h5)
(-5 x -2)= 10
(g x g3)=g4
(h4 x h5)= h9
= 10g4h9
Answer:
m<ADB=70°
m<ADC=110°
m<DAC=45°
Step-by-step explanation:
<ADB=<ABD(being isosceles triangle: AD=AB)
<ABD+<ADB+<DAB=180°(sum of the angle of triangle is 180°)
2<ADB+40°=180°(<ADB=<ABD and <DAB=40°)
2<ADB=140°
<ADB=70°
<ADB+<ADC=180°(being straight angle)
70°+<ADC=180°
<ADC=110°
<ADC+<ACD+<DAC=180°( sum of the angle of triangle is 180°)
110°+25°+<DAC=180°
<DAC=45°
Answer/Step-by-step explanation:
4(x - 2)= 100 and 2(x - 2) = 50.
We can determine that in both equation x equals 27. But, why is the second one half as much as the first problem? This is because the second problem is being multiplied with a number half as large as the first. Since 27 - 2 = 25 and 25 x 4 = 100 and 25 x 2 = 50 these problems hold up to their function.
If x = 27:
<u>4(x - 2) = 100</u>
27 - 2 = 25
25 x 4 = 100
<u>2(x - 2) = 50</u>
27 - 2 = 25
25 x 2 = 50
