Answer:
Square
Step-by-step explanation:
Area of triangle = 1/2 * b * h
= 1/2 * 15 * 25
= 187.5 ft²
Area of square = side * side
= 14 * 14
= 196 ft²
Comparing both areas, it is clear that square have a larger area.
Answer:
Step-by-step explanation:
8.012 x 10^-4
Since you are given two equations
y = 2x - 5
y = x^2 - 5
Substitute into one of the equations...,
;x^2 - 5 = 2x - 5
;x^2 - 2x = -5 + 5
; x^2 - 2x = 0
Hence you factorise the equation..,
; x(x - 2) = 0
Hence....x = 0 and 2
And for the value of y
; Substitute with the value of x onto one of either equations
for...x = 2
;y = 2(2) - 5....y = -1
for...x = 0
;y = 2(0) - 5....y = -5
Answer: 2.45
Step-by-step explanation:
I use pythagorean theorem after i found the total of leg A and leg B
7.5cm
lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
