Answer: 7x-5x(exponent of 2)-21
Step-by-step explanation:
Add a decimal point after the 27 and then multiply in long multiplication. Add your answer and count the decimal points. Then you add the number of spaces from the decimal points to your answer.
Answer C
6 triangles around. 1/2bh=. 1/2 (15)(12)(6) triangles = 540
Bottom base formula 1/2 a p
1/2 (7.5 sq rt of 3)(15)(6)= 584.56
1,124.56
1,125
Step 1: Subtract 63 from both sides.
4x+63−63=18−63
4x=−45
Step 2: Divide both sides by 4.
4x
/4
=
−45
/4
x=

For rectangle
l=3.07m
b=2.24m
so longest side that can be drawn is diagonal of rectangular board
=squareroot l^2+b^2
=squareroot3.07^2+2.24^2
=squareroot9.4249+5.0176
=squareroot14.4425
=3.80
So longest line that can be drawn in rectangular board is 3.80m
