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.
Answer:
B. Data analysis
Step-by-step explanation:
Data analysis is a process of inspecting, cleansing and organizing , transforming and modeling data with the goal of discovering useful information, informing conclusion and supporting decision-making.

Answer:
c
Step-by-step explanation:
D. $2,458*12=29,496*8=$235,968 and then the closest number above that bc its between 8-10 times not 7-8 or 6-8 or something like that.
Length of the outer frame: 4+2x
width of the outer frame: 3+2x
area of the outframe: (4+2x)(3+2x)=15
expand the equation: 12+8x+6x+12x^2=15
combine like terms: 4x^2+14x-3=0
