The perimeter of a triangle with two equal sides is 46 cm. if its base were lengthened by 4 cm and each leg were shortened by 7 cm, all three sides would be equal. find the length of the base of the original triangle.

4cm

Step-by-step explanation:

a+b+c=46 (b=c   two equal sides)

a+2b=46

a+4=b-7

b=a+11

a+2a+22=46

3a=24

a=8 (length  of base after lengthened)

b=19

b=19

8-4=4  (length of base of original triangle)

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
