Step-by-step explanation:
Area of triangular prism =1/2 ×base×height
550=1/2×22×h
h=550/11
h=50m
hope it helps.
All real numbers is the answer
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Answer:
from (-4,1) the line will go up to (-2,2) then (0,3)
Step-by-step explanation:
the slope 1/<em>2</em> dictates that the line will go up by 1 unit for every <em>2</em> units, then we just plot said line from the point given (<em>-4</em>,1) where we go up y by 1 and we go left on <em>x</em> by <em>2</em>
image could not be provided at this time, tho the line will have a slope that is between horizontal and increasing (to the left) at roughly 30 degrees ish
Multiply the equation 2x + y = 1 by 3 to obtain same coefficients of y.
Substract the equation 3x + 3y = 15 from 6x + 3y = 3 to eliminate the terms of y.
Substitute -4 for x in the equation 2x + y = 1 to obtain the value of y.
So solution of equations is (-4,9).
