Its simply 87 + 30, which equals 117.
Answer:
yes because the gift has a surface area of 48 square inches
Step-by-step explanation:
Surface area formula:
A = 2(wl + hl + hw)
2 · (4 · 4 + 1 · 4 + 1 · 4) = 48
Parallel lines have equal slopes. so the equation y=-4x+5.has slope of -4 because this is in slope intercept form y=mx+b where m is slope.
so we know a parallel line will have slope -4
we have a point on the line so we will use point slope formula to solve.
y-y1=m(x-x1) where (x1,y1) is point on line
so we get
y-4=-4(x-0) to put in slope intercept form we solve for y
y-4=-4x
y=-4x+4 is an equation of a line parallel to y=-4+5 passing through (0,4)
10x - 12 + 10 = 18 - 20
10x - 2 = -2
10x = 0
x = 0
4 triangles =4*180°=720°
2 circles =2*360°=720°
Total =1440°
60÷5=12
