Evaluate using suitable identity:<br>e). 102 × 98

chubhunter [2.5K]

Step-by-step explanation:

<h3><u>★ Solution :-</u></h3>

$\sf \longmapsto 102 \times 98$

$\sf \longmapsto (a + b)(a - b) = a^2 - b^2$

Here,

a = 100
b = 2

$\sf \longmapsto (100 + 2)(100 - 2) = 100^2 - 2^2$

$\sf \longmapsto 100^2 - 2^2$

$\sf \longmapsto 10000 - 4$

$\sf \longmapsto 9996$

Keelie has a triangular-shaped card. The lengths of its sides are 3 cm, 4 cm, and 5 cm. Is the card a right triangle?

viva [34]

Answer:

Yes, the card is a right triangle.

Step-by-step explanation:

The card is a right triangle, specifically a 3-4-5 right triangle.

A 3-4-5 right triangle is any right triangle that has side lengths in the ratio of 3:4:5.

The 3-4-5 rule says that any triangle with a side length ratio of 3:4:5 is a right triangle.

So, the card is a right triangle.
