Answer:
(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.
Ratio of DE to BC is 4:6 => 2:3
To find area, we need to raise the ratio of length to power 2
(2/3)² = 16/x
4/9 = 16/x
x = (16*9)/4
x = 36cm²
Therefore, area of triangle ABC is 36cm²
(ii) Ratio of DE to BC is 4:8 => 1:2
(1/2)² = 25/x
1/4 = 25/x
x = 25*4
x = 100cm²
Therefore, area of triangle ABC is 100cm²

The answer is b = 50.
The general form of quadratic equation is
ax² + bx + c = 0.
To write the equation 0.3x²<span> + 5x - 7 = 0 in standard form, you must get rid of decimals. To do that, multiply the equation by 10:
</span>10 * (0.3x²<span> + 5x - 7) = 10 * 0
</span>10 * 0.3x² + 10 * 5x - 10 * 7 = 0
3x² + 50x - 70 = 0
Now compare this equation with the general formula:
ax² + bx + c = 0
3x² + 50x - 70 = 0
Therefore, b = 50.

Answer:
.53
Step-by-step explanation:
Well all you gotta do is basically just divide so it will be 2.65 divide by 5 which would equal the answer which is .53 for all sides
