Answer:
this is your answer look it once.
The base is 3+(x), altitude is x so substitute. Now we know the area of a triangle is base X height X 1/2. Substitute again! 1/2 (3+x)(x)=35. Multiply both sides by 2 to cancel out the 1/2. Now you have (x)(x+3)=70 and you have to foil out the left side x^2+3x=70. Subtract 70 on both sides x^2+3x-70=0. Find two numbers that multiply to -70 and add to 3. Solve (x+10)(x-7)=0. the x value is 7. since you can't have negative length values. Substitute 7 into 3+x for the base so you know the base is 10 and the height is 7.
hey there,
<h2>A)Both pair of opposite side are parallel </h2>
option (A) is correct
Answer:
36 km
Step-by-step explanation:
60% of 60km
60/100
.6*60=36
36 km
17% would be 17/100. or 67%=67/100. 46% = 46/100 (simplify!) see the pattern? hope it helps!
