a triangle has an area of 54 m2 and a height of 9m how long is the base of the triangle entered your answer in the box

Delvig [45]

Answer:
base of the triangle = 12 m

Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m

Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m

Hope this helps :)

Factoring Trinomials

alexandr402 [8]

25 a² + 20 ab + 4 b²

for formula $a^x+bx^ky^k+cy ^{2k }$ find u,v such that: u.v = a

and u+v = b then group according to $(ax ^{2k} +ux^ky^k)+(vx^ky^k+cy ^{2k} )$

= $(25a^2+10ab)+(10ab+4b^2)$

factor out 5a from : $25a^2+10ab : 5a(2b+5a)$

factor out 2b from : $10ab+4b^2: 2b(2b+5a)$

= $5a(2b+5a) + 2b(2b+5a)$

factor out : $(5a+2b)$

= $(5a+2b)(5a+2b)$

Refine:

$(2b+5a)^2$

hope this helps!.
