So in order to find line AC you must find line AD and DC then plus them together.

to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74

Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6

now plus AD and DC which should give u 11.3

A square with a side length of 8 inches would have an area of 8*8= 64 inches^2. If the area is multiplied by 36, the new area = 64*36 = 2304 inches^2. To find the new side length of the square, you take the square root of 2304, which equals 48. The side length of the square becomes 48 inches.

Number 21 please and how to do it step by step

Sonbull [250]

-4y+5x=8
3y-3x=-3 -->    divide by (3) y-x=-1
   then multiply by (4) 4y-4x=-4

-4y+5x=8
4y-4x=-4
---------------
x=4

then plug x=4 in
4y-4x=-4
4y-4(4)=-4
4y-16=-4
4y=12
y=3

solution: (4;3)

the length.of a hypotenuse of a right triangle is 32 inches and the length of one of the lrgs is 18 inches. what is the length,

Elza [17]

Let: hypotenuse = a , known leg = b , unknown leg = c
According to Pythagoras' Theorem: $a^{2} = b^{2} + c^{2}$
   $c^{2} = a^{2} - b^{2}$
   $c^{2} = (32 inches)^{2} - (18 inches)^{2}$
c = $\sqrt{(32 inches)^{2} - (18 inches)^{2}}$
c = 3.74 inches

∴ the length of the hypotenuse to 1d.p. ≈ 3.74 inches
